I admit that I encounter people who make a big deal of how edgy and contrarian they are for speaking out about innate differences in the face of the stifling politically correct consensus that race and sex don't matter at all. It's pretty amazing how they seem to be everywhere, given the supposedly universal consensus rejecting and supressing such edgy, contrarian views.

Have you seen any of these people on mainstream fora? The reason these people seem so common is that you're per-filtering your internet browsing to sites that strongly value truth.
