How to come out

When you tell her, don't ask for her blessing, just express your views logically. Explain why you want to have a career in politics, why you think a class-less society is a good idea, and why it's safer for you now than it was in her totalitarian country. That being said, you don't have to convince her. You might feel like you do, but you don't need her full backing to do what you like.

Also, unless you feel guilty for not telling her, you don't have to tell your mom your life plans. You're in change of yourself and if you don't think she would support you, then don't beat your head against a wall trying.

Coming out about political views? Why would that matter, at all? Also, I'm guessing that you're young, so something tells me that your idea of a stateless society won't last long.

I'd just tell her, she'll probably be fine. That said, how the heck can you get into politics if you support a stateless society? (and anarchy would never work, for about a trillion reasons. There's a reason there are no anarchist non-states in the world.)
