I got out of an abusive situation too and I learned a lot about myself and my past choices by going to some of the web sites.
I've read all of the posts and I think that this member is full of rage that is so overwhelming that she is choosing different forums so that he can instigate arguments. The post somewhere above made it clear that he didn't want to be personally addressed and this person just continued and kept posting directly at that guy.
He says, "My posts might irritate some, but at least I make people think and sometimes outside of the box." I disagree with everything that he posted and they don't make me want to do anything other than feel pity his poisoned rage.
Get some anger management because you are being eaten alive by it.
