You say that religion and (it seems) discrimination are cornerstones of conservativism but I would categorically disagree with that notion. I hold many of the classical conservative values (limited gov, thoughtful regulations, primacy of the constitution, belief in public investment in education, health care, defense, and research to support the public good etc) and would consider myself to be at least an economic conservative in the classical sense, yet I am an atheist, am socially liberal, and do not support racism, sexism, or xenophobia in any way. I would say some of these negative ideas are represented by the Republican party in its current incantation, but the ideals of the Republican party and conservative ideals are not necessarily one in the same, in the same way that the ideals of the Democratic party are not equivalent to classical liberalism.
