Tbf the people who are against rationalists describe themselves as sneering. See r/sneerclub

First off, it's not my belief system. I'm not a rationalist.

Second off, I didn't call the whole audience "sneering POS's". I only implied it. Regardless of whether they're 5% or 50% those types are sufficiently plentiful in the comments, here and elsewhere, such that anyone posting stuff that's against the grain will be quickly predated upon by them unless their take is hedged in a nearly airtight manner.
