I don't like "orthodox" terminology, but I acknowledge that it exists. I'm socially conservative in that I support a socially conservative society, but I am not politically conservative because I think government has no right to actually force anyone to participate in a socially conservative society. If my neighbor is not aggressing against me, or someone else, with his vice, I have no right to use force against him.
Of course, I do believe that abortion is an act of aggression, which does create some friction between me and most non-Christian libertarians. So I do believe abortion should be illegal even while most other "Liberal" lifestyles such as gay marriage (Government should stay entirely out of marriage), drug use, prostitution, and all sorts of other behaviors I am ethically opposed to should not.
Most Evangelicals are socially conservative, politically conservative, and even worse, neoconservative on foreign policy. See my "Defending our freedoms" thread...
I can live with social conservatives who aren't foriegn policy "Conservatives" but there aren't many of those. The best example I can think of is Pastor Chuck Baldwin, and while he's not Ron Paul, I respect him a lot.
