I don't think you can easily lump all of NRx under one banner. Criticism of democracy is fairly accepted on LW, and HBD (as an 'is' statement, not as a justification for discrimination) is seen as plausible. OTOH I don't think there is much support for homo/transphobia here, and its certain comments on this subject which seemed to get an unreasonably large number of upvotes.
