Trans people don't usually claim there's 600 genders either ... Makes sense seeing as the exclusive point is to move from 'man' to 'woman' etc and never 'man' to 'zee them bacon sandwich'..
I THINK IT’S CRINGEY WHEN PEOPLE WHO AREN’T TRANS PUT THEIR PREFERRED PRONOUNS IN THEIR SOCIAL MEDIA BIO; THE VAST MAJORITY OF WELL-PASSING TRANS PEOPLE I’VE SEEN DON’T DO THIS
