You're unable to see the difference between "banish heretics" and "banish cult recruiters"? Or, more to the point, between "banish heretics" and "forbid cult recruitment"?
(I am not sure how good a metaphor either of these is for neoreactionaries on Less Wrong, but the two are quite different things and it's in no way ambiguous which Viliam is arguing for.)
So let's take the Cult of Cryonics. What do you think "banish cult recruiters" might look like? I would bet that it would look like prohibiting discussions of cryonics and be indistinguishable from "banish the heretics" in practice.
And of course NRx isn't a cult, Yvain's offhand comment notwithstanding.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
