By the way before I get downvoted for my views, I am merely pointing out that actual conservatism is a position of Federalism rather than a position on a particular agendas of certain groups.
That means a government should be closer to the people it obsensibly represents and decision should be made at the lowest level until such time as it affects a higher level. For example, if California wants to legalize heroin, that's for California to decide -- it has no practical effect on people in Louisiana.
The problem with many social conservatives is that they are intellectually inconsistent -- you can't call for government to enforce what 'you' want but then call for smaller government when it comes to what 'they' want.
It's a question of the scope of government and at what level government ought to be acting -- it really isn't about specific issues but the bigger question of "Is this the role of the Federal government."
