So what gives any group of people the right to decide what happens with another persons life? Can I impose my beliefs onto you personally? If not, can I delegate that to a group of people to do it for me?

Yes, Brexit would not have happened. Hitler wouldn't have been voted in democratically either. My point is that voting is coercive as you are using a ruling gang to carry out your wishes. If you think that is moral then I can't really argue with you.
