I've seen that happen. I'm such an observer of human behavior (trying to understand it, failing always!) that I start to categorize things. I can tell how something will go, more or less, by certain variables of the people participating.
I'm sorry he didn't apologize to you, it may never have occurred to him (because it was online, and public).
Part of our challenge as individual ASD types is to determine which circles of bullsh** we cannot tolerate. We are more finely attuned, I believe, and less capable of having things roll off our back.
I tend to treat Facebook like a grand, neverending cocktail party. I don't talk about things there that I wouldn't talk about at a big cocktail party. Yes, I've been to cocktail parties where there are two guys arguing vociferously over something over in the corner, but just like on Facebook, they tend to just be selfish a**holes.
