You’re not the main character,

You are. You are also responsible for your own choices whether you admit it or not.

That is the most selfish possible way to approach life.

If taking responsibility is selfish, then selfishness is a virtue.

at least you’ll be able to vote again and you might actually get to negotiate for things that make people’s lives better.

They are already threatening you with Trump if you don't vote for them and don't want to compromise. So about that "you'll be able to vote again" - I think that's true, but since that threat works, that'll likely be the same kind of choice over and over. When you agree to get owned for protection, you usually don't get owned just once.

Selfish naive children.

For fuck's sake, are you 16?

How can a grown person be that arrogant without knowing shit about game theory?
