The categorical goal should not be a "successful community", but rather a truly rationalist community. As such the process of truth-finding should not be compromised by any social "niceties". Now, I can bear some extra effort on the writer's part, but if you feel the pressure to please everyone, it is already a step in the direction of self-censorship, which should not be tolerated. No policy here should step on such a slippery slope, for there is a reason why they are called such.

And an explicit ban on any topic is (of course) categorically not acceptable - be it PUA or whatnot; as such is already a huge slide down on said slope. I am surprised there is not much more of an outcry following such a daring suggestion.

Rationality encompasses all - it has no taboo themes. Neither should you or this community.
