The thing about political choices is they present themselves every step of your life. There's no permission to let up or retire; you have to keep negotiating them through life.
Because you're not, after all, the only star in your universe. You can't make your choices in abstract or in a void - say "I'm A, B and C" and believe it to suffice forever. Each choice is to be made within a context, with a set of external factors to contend with - social norms/prejudices, families, work.
Sometimes the battle seems almost not worth it because you yourself don't know what's at stake; what would happen if you surrender. Only a vague reluctance to fit into the system.
