Honestly I just wish both sides of the major parties leaned far less authoritarian. As it is neither are worth a vote, and this third party thing will take forever to get off the ground. I just hope I see libertarian leanings in real offices abundantly before I die.

But to answer your question, people hate other people who are different, and want the law to do their dirty work. Result is everything gets made illegal and for-profit prisons and drug lords reign.
