But of-course I don't think sharing the name is rude, it's a basic personal reference. It would be rude if it's followed by "I'm straight" or "I'm a woman". As for pronouns, in most languages, you can know the [grammatically] correct gender automatically from the name. And if you don't, most grammars have middle or neutral gender, so that can be used. The issue here is that we shouldn't bother other people with our gender identity.
