[EDIT: Just to clarify, before I draw more heat than I deserve, I think SR's outbursts are unacceptable, but the second half is more aimed at the folks bashing atoon, and pointing out why they shouldn't, not related to the comments atoon made that drew such wrath]
"Some people who engage in it just to be an arse"...
I think you just described SR's problem there....
He engages in it (unjustified, as this case has pointed out) just to be an arse. It doesn't matter if he wins or loses, he's still an arse about it. At this point skill doesn't matter. He's just being a jerk. I think that's why he gets so much "attention"...
Another matter:
If somebody IS so anti-social, and such a bad personality, it's not much of a stretch of the imagination to think that nobody wants to have anything to do with him, even his family members or friends.
That's not "dragging his family into it" per se, but rather driving home the point like saying "When he was a kid his momma had to tie a porkchop around his neck just to get the dog to play with him!" -- it's not about the momma, the dog, or the porkchop.
So to me that was not "dragging his family into it" -- a silly notion. Mention of them was secondary to the point: The people he knows are probably happy he's being a jerk online, rather than to them.
Had to back atoon up on his "never dragged family into it" point. The rest he's on his own, but don't rag on him for insulting SRs family, because he did not.
