In addition to the arbitrary rejection of science, today’s unhinged left is characterized by a toxic intolerance of dissenting viewpoints.

Just consider the plight of one-time liberal icons Elon Musk and author J.K. Rowling, who’ve been viciously smeared for saying there are only two sexes — men and women — and that there are distinct differences between them.

Musk came under fire from leftist Twitter trolls for suggesting that transgender activists promote the contradictory opinion that gender differences don’t exist at the same time they insist sex-change surgery is an imperative for anyone who wants it.

“We are simultaneously being told that gender differences do not exist and that genders are so profoundly different that irreversible surgery is the only option,” the Tesla billionaire (and potential Twitter purchaser) wrote in a Twitter post on Saturday.
