Well, it’s always nicer to use what they believe is ok, even if you don’t
But if it’s get to a limit like
“I’m dreamsexual and chocogender.
My pronouns are dream/chocolate.”
Then yes, that’s fine
A lot of people with neopronouns use “normative” pronouns as well (he, she, they) so use those, maybe?
For example, since my phone autocorrect hates neopronouns, I usually use whatever other sets of pronouns they’re okay with
HYPOTHETICAL QUESTION, SO IF I DON’T BELIEVE EVERY GENDER IS VALID, HOW WOULD I GO ABOUT RESPECTING THE PEOPLE WHO IDENTIFY THAT WAY WITHOUT HAVING TO GIVE UP MY BELIEFS? FOR EXAMPLE, IF SOMEONE USED NEOPRONOUNS AND I DON’T BELIEVE IN THOSE PRONOUNS COULD I JUST CALL THEM BY THEIR NAME TO KEEP THEM FROM BEING MADE UNCOMFORTABLE?
