The moral weight of democracy is heavily overrated. Of course democracy is better than autocracy, all other things being equal. But I don't think a democracy that starts wars and bombs a new country every other year is morally superior to any relatively peaceful autocracy. Rather the opposite.
Try holding up a sign in the street anywhere in China that says anything remotely critical of the Chinese government. Or live in China and post something online remotely critical of China. You will be arrested, thrown in jail for years.
Democracy isn't just having an election every four years. We have rights that we shouldn't take for granted.
