I think it's more accurate that both the extreme right and extreme left are the parties of authoritarianism, and the center is about freedom. Leftists want to police what you say, what you think, how you earn your living, and who you associate with. Rightists want to police what you believe, what you do with your body, what substances you inhale, and how you travel. Both sides would do well with a chill pill and the idea that people could be or believe differently than you without being a threat.
