If one does not believe in the statement in the Declaration of Independence, that ALL are created by their Creator, one does not believe in life, liberty and the pursuit of happiness.
While conservatism and the Declaration of Independence are not mutually exclusive, the Declaration of Independence is not about conservatism. Conservatism is about smaller government, lower taxes and self reliance.
I'm a conservative and I believe in and support the D.I. and Constitution. There's nothing in either that says I have to accept your views -- or anyone else's -- as to Whom or What that Creator may be, or any of the specifics that derive from that belief. I'm with Poser on what defines "conservatism." Specific religions or religious beliefs have nothing to do with conservatism or the Constitution, as it's clearly spelled out in Amendment I.
