[int_19h]

You'd be surprised. I've met people with preferred pronouns like xe who were outright offended at the use of they/them, because "that's not my pronoun".

Different category of objections, so not really relevant to the point, which was about the objection to their use in general, not about any given person.

[int_19h]

But it's not really a "universal pronoun" if you can't use it to denote any random person without offending them.

That's moving the goalposts.
