Yes, yes, okay, okay, pax!!
I know, I know, all you did was ask, “Why was So-and-So banned?” It’s just that it seems that for the last month, there’s been a constant stream of “Why was So-and-So banned?” ATMB threads, some started by actual innocent newbies, but some by posters who should know better. And before you know it, the thread has escalated into a name-calling slapfest, because frequently some people feel a deep psychological need to use the opportunity to take a few potshots at the mods and admins, and next thing you know you’ve got Pit threads all over the place. And also, sometimes those threads, both ATMB and Pit, are suspiciously chock-full of just-registered newbies with inflammatory or derisive user names. It seems like the “Why was he banned?” question just gives evildoers an opening for mayhem, which they pounce on with delight. So I was just trying to get the lid onto the grease fire before the stove exploded, okay?
And hey, when I talk down to people, they generally know it immediately, because I always preface my remarks with, “Hey, stupid! Yeah, you with the pointy head!” But I didn’t say that to you, now did I?
And I did give you the benefit of the doubt; I treated you with the respect I accord a senior poster. All I gave you was the “word to the wise” Cliff’s Notes version–the wide-eyed newbies get the whole lecture. 
I’m frustrated with these people, too. I don’t like driving all over Google looking for a GQ answer for somebody who’s banned by the time I get back. That actually happened to me once, and man, was it annoying! Stupid clump of fecal matter. Go back to the rectum from whence you came.
And yes, in theory I do agree that it’s always good to Fight Ignorance, but the SDMB is also about relationships with the other posters, and it gives you a warm feeling to find an answer for somebody, and then later he finds an answer for you, and so it goes. This chain of–dare I call it “friendship”?–is broken when you come back with your answer, only to find that the OP now has BANNED under his name. “Oh, I guess we won’t be friends after all, he was only a troll [sigh].”
As for “spending…time trying to help these sociopaths”, golly, Una, I don’t really believe it’s possible. There’s just always going to be a percentage of the human race that gets its jollies out of smashing the pumpkins on your front porch, and the best you can do is just work around them.
[Fed Ex truck pulls up outside TubaDiva’s house, delivers 20 large boxes of Godiva chocolates, with a red and white musical teddy bear; Tuba squeezes its tummy and it sings,
“All around the cathedral
the saints and apostles
look down as you hear our prayers,
Although you can’t see it,
you know they are smiling
each time Tuba shows that she caa-aaarres…”]
