This is a good example, I think. Just about everyone insists that other people use their preferred pronouns; it's just that most of us are lucky enough that ~everyone automatically does so.

If you would complain if a colleague persistently referred to you as 'she' (if you're a man) or 'he' (if you're a woman), your real argument is not that nobody should be 'forced' to use a certain set of pronouns when referring to another person.
