Ex-poster razordance tripped my trouble alarm from the git-go:
IOW, IMO he started as more of a “concern troll” than a flaming jerk. And he was smart enough to not be completely clueless or brain dead about his OPs. Any one of them in isolation would have been innocuous enough.
It looks to me like he started feeling his oats a bit too much and finally with the abortion thread let his inner jerkitude come shining out when his earlier efforts to sow arguing just resulted in our usual wall of sensible, full-length, if rather partisan, responses.
Either that or he finally had a posting session while wasted.
In any case, his banning is no loss for the rest of us.
