I don't quite get your stance. You're free not to use those words. It's not like it is against the law to not use those pronouns. It is a simple and nearly effortless courtesy, that you can ignore if you want, with the consequence that people may think you're a twat and treat you accordingly.

Like, you're not mandated by law to greet someone with "good morning" instead of saying "fuck you". Yet it is widely understood that if you do this and refuse to say good morning, people will be upset and become hostile towards you. It's a perfect analogous situation. I'm not really sure what you want.
