Is there really ever any reason to kick a polite, well studied and respectful person off a public blog just because they happen to disagree with the majority opinion? I don't think so!
But I saw it again today at a place I used to frequent. It was pretty sad actually. A guy that was respectful, polite and in no way derogatory got banned simply because he wasn't saying the "right things" in the way that the majority of the "ruling party" wanted them said.
They basically got tired of talking to him, claimed what he said was "poison" and banned him. No warning, no "please refrain from speaking about this topic here", nothing.... just a sudden "No blog for You"
