The initial political ban is to stop the bitter argument around the presidential election and both parties. We don't want to extend the ban too much beyond that.
Many topics such as taxes and health insurance can't avoid politics completely, so, usually if a topic wasn't created to discuss politics, no important political figures or parties involved, we don't want to intervene. There are also discussions about UK and AU politics, but there are no arguments, we didn't moderate them either.
We try to give the members maximum freedom to discuss things while keeping the forum a friendly place.
