What's the ultimate taboo he's committed?
I don't mind anyone agreeing or disagreeing with me or anyone else here. This place is to share minds with each other.
But, personal attacks against anyone here is taboo. You just don't do it. The post I linked to above was a personal attack and I vigorously objected to it and (see the posts below it) made my position as clear as I could.
I don't know (nor want to know) anything about what happened at VoA regarding his ban there. I certainly don't object to his debating subjects that everyone here disagrees with. This is a good thing and should be encouraged.
This is supposed to be a friendly place. Disagreements are acceptable. Personal attacks are not.
