Honestly though, it’s a good way to weed out that 70% with antiquated conceptions is gender norms which will probably cause problems later in the relationship anyway. If they get that offended over splitting the check in a first date, they’re probably gonna hold you to unworkable heteronormative expectations later, too.
If someone tells me to use a certain pronoun I will, but my default has been “they” for a long time now. Gendered pronouns in general are a terrible idea, linguistically at the very least.
