Who are "we, the good people, who force others" then? If democracy is the rule of majority and the majority of people are "not good", then you're ruled by people who are "not good". If government enforced people to do "good" (not smoke marijuana, preventing gay people from reproducing, allowed building with asbestos), and then the changed their mind (allowed to smoke marijuana, allowed gay people are to reproduce, banned asbestos), did they enforce the "good"?
