Until all power reserved for the states is given back, social issues must be fought on the national level.
Liberals have made an avocation, over the last 60 years, of nationalizing everything while telling conservatives that conservative issues are state issues -- and then suing in federal court to have their own way.
Turn about is fair play, but in the longer run you are right. The problem right now is to subdue the knee-jerk federalizers and internationalizers, who are really just all about amassing power. At some point their creation becomes a black hole of despotism, but they don't care -- they want their fix, like junkies.
