There is a method to it. If one strives to keep rights and liberty at the top of the priorities list, it can work. You may be personally against pornography, but enabling anti-pornography laws goes against the right of free speech and freedom of the press, so what do you do? You do not make laws against pornography, because it tramples over the rights of others to enjoy it. Above all, the system should not respect the beliefs of those who seek to take away rights.
But that doesn't always work.
What about the right to sell crack cocaine to school kids, which is a fundamental right to do business?
What about the right to freely distribute Oxy-contin to poor people who can't otherwise afford it?
What about the right to engage in underage child prostitution, which falls under free association?
What about the Carthaginian right to sacrifice babies, which is fundamental to both religion and families?
What about the right to refuse to pay taxes to the government if you think it's wasteful or corrupt?
What about the right to walk into a courthouse with a General Electric mini-gun and twenty pounds of C-4 to protest a law against bringing mini-guns and explosives into the courthouse?
What about the right to slaughter and eat any neighborhood pet that wanders onto your lawn?
Under your method, anyone who is against any of the above shouldn't be allowed a say in making laws, which would leave us with laws made by people who should be in jail.
