So you're opposed to using the tax code to get people to marry? To stay married? To have kids? To go to Christian schools? To tithe? To own a home? And all the other behaviors needed to ensure a moral society. (which is the government's job)
IMO, some behaviors should be encouraged by the government.
Since WHEN are those behaviors the responsibility of the government? They most definitely are NOT! And that is one of the main ‘progrommes’ (too) many people are using to absolutely DESTROY what once was our nation.
