I agree that you are legally compelled to pay taxes, but why do you say that you are morally compelled to do so? Democracy is a kind of majority rule, isn't it? If the majority votes to take 50% of my income in taxes, and uses the money to start wars around the world, I stumble when it comes to saying I'm morally obligated to pay those taxes. Thoughts?
