One could argue that legalizing gay marriage and marijuana are conservative standpoints as that means less government limitations on your personal life.
I’ve wondered about that myself. Unfortunately, for some (possibly arbitrary) reason, the Republican party seems to be intertwined with Christianity. I say arbitrary because I have many conservative friends for whom their one gripe with the Republican party is its immersion in religion.
I’ve often wondered what the U.S. would look like if it happened to be the liberals that were embroiled in Christianity.
