To be fair, the equivalent solution for the name field example would be solving it by insisting everyone specify how many names they have before letting them enter their name - there's a reason that isn't the recommended solution, people don't want to deal with minutia that doesn't matter to them, one field works fine for everyone. The obvious solution is to just not use pronouns - it's a messy part of the language that is currently in flux, so why wade in? Obviously, some sites are dedicated to these issues, so they can justifiably ask on sign up, but if you don't _need_ to care about people's personal details, better not to ask at all.
