I think the problem is sometimes...emotions run high..and rather than discussing something...two enities are flingging crap at each other. This can potentially be a problem for the owner of the website. So don't get uppity with TJ when he says there needs to be rules of engagement. The reason this works at all for these types of discussions is because we aren't in each others presence. But typically...WRP type topics don't do well with live company. Make an effort to be good natured even when you disagree with another.
Remember...the secret to working with another is to at times be able to tell the other to go to hell...but make them feel good about the trip.
