... because some people actually ask to not be called "cis".

I read a satire article on the same page and first thought this was parody, too, but no.
It is totally serious.
They actually claim the Left, who submit to all their language rules, are still not good enough allies, because they actually have the cheek to demand that they not be called names they hate - apparently, if lowly cis people call others names they don't like that's "deadnaming" and "transphobia", but heaven forbid a trans ally actually display a will of his own and doesn't want to be called cis.
I wonder when the Left will realize they'll never be good enough and (hopefully) decide to just give it up.
