What'd put this argument to bed in a hurry would be to know who exactly is doing the complaining in a transparent manner. It'd also allow for the conversation around the issue to continue in a more honest and productive manner. I don't think many people would have as much a problem, including myself, with discussing more moderation if we knew it wasn't just people of a certain political bent complaining about it.
But that doesn't happen. Even though it doesn't take a genius to know harassing people on the forum is already a violation of a basic rule in nearly any online community including this one.
