Let’s talk about tolerance.
I was a hippy back in the day. I remain a “liberal” to this day. I am personally tolerant of things I dislike when manifested or displayed by other people.
I believe that fat people look ridiculous in skimpy clothing. I am fat, and I do not wear skimpy clothing. Still, I tolerate fat people who do. I do not point and grin, admonish them, or otherwise display my inner dislike.
I further believe that people who would judge others, especially those who would condemn or ostracize or attack others, on the basis of race, gender, or sexual orientation are fucktards. But I will tolerate them. In other words, if you make nasty comments about other people based on your bigoted opinions, I will usually just walk away. I’ll tolerate you.
Sometimes I may actually attempt to disuade you, or otherwise fight ignorance. But mostly I’ll tolerate and ignore you. Personally.
I’ll also tolerate expressions of political difference, provided they are respectfully couched. Perhaps we may even debate such issues while retaining respect. I welcome such exchanges.
So, yes, liberals like me believe we are tolerant.
But tolerance goes only so far. If you try to force your bigoted beliefs upon me, I will feel no obligation to remain tolerant. And when your bigotry infuses your politics, I have no tolerance at all.
However you conflate “Liberal” and “Democrat”, neither expresses a political ideal that would reduce or remove rights from another human being. “Conservatives” on the other hand condemn things like same sex marriage, and “Republicans” make that a plank of their political platform. I recognize that some Conservatives and some Republicans do not share this bigotry. Still, there seems enough evidence to conclude that, in this regard at least, “Conservative” and “Republican” correlates highly (but admittedly not exclusively) with bigot and fucktard.
I make no claim to be tolerant of such.
That said, I still fail to see how school children picking on a classmate over perceived differences has any correlation to liberal hypocricy over intolerance.
