God, we trust. Mere mortals pay cash.
I’d suggest that the OP has encountered far more of the former, but remembers more vividly the few encounters he has had with the latter.
Religious people don’t have any evidence that God exists, sure. But likewise, you also don’t have any evidence that God doesn’t exist. The more pertinent question would be, why should religious people have to put up with you?
Answer that question, and you’ll also have the answer to the question you asked.
Sheesh, the old prove a negative. Really?
I put up with people that do like cats, and don’t like dogs all the time.
Even though they are objectively wrong, I don’t hold that against them. 
But the OP keeps seeming to want to throw in something entirely different than tolerating other people different than himself, he wants to sneak in commentary about the intolerance of some others.
There is a wide difference between holding a different opinion on a subject, and imposing your opinion on others.
If someone wants to feel that something is against their religion, so will not do it themselves, or even recommend to others that they do not, that is fine, they are free to live their lives and advocate for what they believe.
If they want to impose their beliefs on me, then that’s a whole different debate, not one that was asked in the OP, even though it is one that the OP has come back to insinuate on a few occasions.
So, I would ask the OP to clarify themselves. Is this thread a question of why we tolerate other people who have different beliefs than we do, or is this thread a question of whether we should allow others to impose their beliefs on us? Those are two different and largely contradictory debates, and trying to have both of them in the same conversation can only lead to confusion at best.
Oh, and it’s “Sky Fairy”, not “Sky Giant.” Didn’t you even read your Atheist Agenda 101 summary?
But that doesn’t stop even those that are well meaning from expressing their personal thoughts and feelings about their beliefs and obliquely quizzing you to see which team you’re on. If they get no response, often that just serves to pique their curiosity even further.
No atheist, to my knowledge, has ever annoyed a religious person by a heartfelt, “There is no Plan. Shit happens.”
They didn’t used to. Need I remind you, there remain places in many parts of the world where they don’t.
I agree with you. Isn’t that enough? 
Seriously, I get your frustration. It amazes me that people are religious. It amazes me that people would vote for Trump. It amazes me that people enjoy watching sports, or listening to Frank Zappa. There is a part of me that just wants to go on picking at it and saying, “But whyyyyyyyyy?” But there really is no answer.
All you can do is hang on to what works for you.
You don’t have to defend it.
I feel confident that I’m speaking for a large percentage of religious people, probably even a distinct majority, when I say that we don’t care what you think.
Well, you don’t know for a fact that there is no creative force governing the universe any more than “the Religious” know that there is. If people are aggressively pushy about religion, though, I agree that you can aggressively push back.
However, your statement indicating that you are “tired” of even “your everyday law abiding person of whatever religion” troubles me. The fact that you feel entitled to tell off even these people smacks of a level of self-importance that, to me, is unacceptable.
Is science just atheistic evangelism? Just another fringe philosophy that Christians have to tolerate?
He belongs to a different sect of Atheism.
Probably the No-Jehovah Witnesses.
I’m an atheist, and I think there’s many people that absolutely need religion. Especially the “If there’s no God, why be good?” types. Yes, this is essentially an adult version of Santa where you better be good for goodness sake, but I don’t want these people thinking they can do whatever they want as long as no one’s looking.
It should be noted, though, that for many of these types, the only “bad” things they’d do would just be…things a lot of non-religious people do. Not things like murder or other crimes, but just things like having premarital sex (if one is Christian) or eating pork (if one is Muslim.)
I feel like an awful lot of religious people don’t repay that respect. When something bad happens, I hear a lot of, “It’s God’s plan.” type stuff from people that know for a fact that I’m an atheist.
When I’m at a religious person’s funeral, I don’t tell their wife, “He’s gone now, there is no afterlife.” out of respect, but there doesn’t seem to be the same level of respect, in general, on the other side,
This is anecdotal, of course, but it certainly seems pretty prevalent.
No, science is not atheistic evangelism. Science works equally well with or without a god (or God or gods). Some religious people are anti-science, but then, so are some atheists. Opposing or being intolerant of an anti-science stance is not at all the same thing as opposing or being intolerant of religion.
I myself am a theist and a scientist. I have a lot less tolerance for anti-science theists (of which there are, unfortunately, a large number) than I do for atheists who accept science.
(my emphasis)
Umm, you might want to learn a little more about the various varieties of atheism and agnosticism. Strong or positive atheism is one strain that positively asserts that gods do not exist. Weak, or *negative atheism, says that there is no evidence that gods exist, and no reason to think they do, but that it’s not a premise that can be completely ruled out. It’s the difference between “I believe gods don’t exist” and “I don’t believe gods exist”. Negative atheists, such as me, say that positively asserting “Gods don’t exist” is as unreasonable and unproveable as asserting that they do.
As to the original question of why we have to put up with religious people, it’s because there are more of them than of us, and they have a right to their beliefs. We do not have to put up with them when they attempt to impose those beliefs on us, via proselytization or policies; in fact, that’s the raison d’etre of groups like Americans United for Separation of Church and State, and the Freedom From Religion Foundation.
I’m not saying theist are horrible people, in the OP i specifically mentioned most are probably nice people. But for me to have even acknowledge that their belief in the supernatural is anything but silly nonsense such as ghosts, UFO abductions, or the tooth fairy, seems absurd.
As a Christian with atheists and Christians aplenty in my family and social circle, I am trying to think up a suitable post here, and it’s tough. All I can do is bullet-point style:
-
Atheists and religious people can be just as diehard and genuine in their beliefs as the other. So when an atheist insists with vehemence that God is fake, he is entirely sincere; when a Christian insists with vehemence that God is real, he is also entirely sincere. Neither side is putting up a facade; they are presenting their 100% sincere view.
-
I agree that atheists are in general less pushy about their views, and this is partly because in some religions there is a mandate to spread and propagate the religion whereas in atheism there is usually no such mandate.
-
It is indeed true that religion is a major driver of warfare, conflict and death in the world.
-
America is not 70% Christian; as some may claim; a great many of those are Christian in name only. The actual figure of genuine serious Christians must be only a fraction of 70%.
Their actions define them. Your reaction will define you.
No True Scotsman fallacy, here. You don’t get to define who’s a Christian anymore than Bacon Cheesburger gets to define who’s an atheist. In 2019, 65% of Americans polled described themselves as Christians; ergo, Christians make up 65 - 70% of Americans.
