why...?
Well the fact that you say we should look at "the man behind the keyboard", we should look at the bigger picture, saying he felt betrayed, and talking about belittling him to his "male core".
You seem rather pleased he's decided to leave, whether he was pushed or not.
I personally think he did a good job on here. Most online forums are full of trolls, who go online to just slag people off. This forum isn't like that. I think it's because the mods are on the case. Even if that does mean the odd edited post.
People can be very brave/rude behind the keyboard....yet wouldn't dream of saying the same things face to face with people.
