Initially, I wasn't going to respond to that part, but....

It leads me to ask, "If two grown men on a site can't have a rational conversation (heated or otherwise) without one one of them getting banned (or uninvolved 3rd parties 'jumping on' one of them), should a grown man care if he gets banned from such a site?"

Now, that's not to say I want to be banned; just that all ongoing conversations are 2-way exchanges and I have better things to worry about than if random strangers get butthurt over random comments on the interweb.
