Politics is a system for attempting to get along with people whom you do not like. Politics goes wrong when that attempt includes coercion.
No one needs politics for dealing with those we like. Getting along with them comes automatically.
The best political system is the one which allows those who really don't like one another to still live their lives peaceably in the same space.
Authoritarianism doesn't work because it usually forces those people together in a way that makes both sides more unhappy than they were before.
Only in a libertarian society can people be free to associate in any way they choose, as long as no one initiates force or steals.
If you truly dislike someone, minimize your dealings with them, and do not cause situations which escalate the dislike on either side. When you must deal with them, do so with the same respect that you would want, and then move along. Don't dwell on the fact that you don't like them. If you can ever grow past the need for your dislike, you might just find that they are not so bad after all. It has happened before for me.
