This is clearly a case of you giving someone on your side of the political debate more slack, no question about it....your bias is showing.
You do realize the only time I PM someone a warning note is AFTER I've gotten a complaint or it's just so blatantly obvious (YOU PIECE OF SHIT kind of thing)...
I have no bias towards either side - in this aspect. In fact, I'm more likely to say something to those I do agree with...mostly because there might be PMs already flowing.
