These are people getting their panties in a twist because they are being reminded that other people can choose different pronouns.
That’s nothing new. The vast majority of far-right reactionaries know exactly zero trans people. They’re getting upset because a stranger, who exists entirely in their imagination, may have an opinion about their own body that the far-right have not approved as “okay to have”.
Of course, there’s probably deeper reasons that they won’t say out loud. What if they accidentally find a “man” attractive? What if they have to treat a casual acquaintance with basic human decency?
