I'm a libertarian/conservative Republican, leaning more towards the libertarian viewpoint.  I'm secular and lack the religious impetus that propels a significant number of conservatives.  Accordingly, I don't really think that someone else's lifestyle affects my liberties, and I never objected to the idea of same sex marriage.  Of course, conservatives in general are more comfortable with same sex marriage than they used to be, so  I may not be as divergent as I used to be.
