What current "conservative" policies "regulate the behavior of others"?
Seems to me it is primarily wild-eyed liberal zanies who want to restrict tobacco use and curb Non-PC speech. They would probably ban heterosexual marriages with more than 2 children if they could. And prohibit any public discussion of religious moral values. I understand there are some who want to ban religious private schools.
Liberals are every bit as moralistic and judgmental as any traditional conservative -- they are just moralistic and judgmental about different things. Seems to me that compulsion seems to be a liberal characteristic: steadily raising the levels of taxes and regulation, forcing people to associate with those that they don't wish to associate with, that sort of thing.
