Well, I don't disagree with the folks who are saying that the root of the problem is the person, however, I'm not playing D&D to fix people.
I don't really understand what you're saying there. No, of course you don't. Neither do I; I certain;ly hope my post doesn't imply in some way that I do. I was merely refering to one's choice of social companions, and basing it on the person and not on the fact that they have something in common with someone who caused offence.
I'm talking about a social interaction with other human beings, and what I personally consider an acceptable way to interact with them; and that I'd consider being "lumped in" with problem people for convenience's sake to be beyond my personal limit of socially acceptable behaviour.
Your standards, obviously, differ greatly to mine. That's not a bad thing - different strokes, and all that. Nobody requires that everyone have the same opinion on everything. But they aren't compatible standards for the purposes of social interaction.
You gotta stand for what you believe in. You're doing exactly that; I'm merely stating that I believe something very different.
