Well, I don't have any idea what to do with the guy who just lies into my face. Especially when he got the power to ban me just because he feels like that.

Apparently, lesswrong.com is not a place for any discussions.

occasionally appending "only an idiot would say that" to your statements

Well, this is just a lie. Other points are misleading or outright made up too, but this one is particularly blatant.

On the other hand, jollybard call me a jerk and an idiot for a few times, and you paid zero attention to it.

But who cares, right? Long live the echo-chamber.
