The point people are making is that once we start making judgement calls like this there will be more and more calls from the community to make more judgement calls to increase the net and shutdown other types of sub-reddits that they disagree with.

It is however a fantastic reason to talk about the potential consequences of that infrastructure, and perhaps to arrange for safeguards against the unwanted scenarios. This is what some of us are trying to do here while you are clamoring to (extending the metaphor) put everyone in jail who may one day murder someone.
