"Sex realist" is an interesting phrase. So-called "sex realists" call themselves that because they think they're acknowledging that sex is "real," right? But it reminds me of two other "realisms" - race realism and capitalist realism. Sex "realism" like race "realism" takes a couple actually existing traits about a given population like skin color or secondary sex characteristics, and runs wild with that, over-generalizing to the extreme and claiming bullshit about IQ, emotional disposition, etc. in order to prop up their fascist ideology. As for capitalist realism, well, it's quite apparent that for the "sex realists," it is easier for them to imagine the end of the world than it is to imagine the end of sex. Sex realists indeed...
