That’s it.
They don’t exist - any more than preferred adjectives, adverbs or nouns exist.
Even people who don’t like them still seem to think they exist.
Language is a shared, collective endeavour that belongs to all. It’s not a pick’n’mix for individuals to choose and change at will. For words not to be garbage they have clear definitions - in this case she for females, he for males, they (singular) for sex unknown.
Saying my preferred pronouns are she/her, even if that doesn’t fly in the face of reality, is no different to saying my preferred species is human, my preferred adjectives are sporty and lush.
It’s nonsense. Nothing to do with being kind or they don’t affect me, or I don’t mind if others do but I won’t. It’s nonsense.
Let’s make 2025 the year we kick this nonsense into touch.
