The thing is, political views do make up a great portion of your principles and identity. I have seen some Christian liberals just as I've seen agnostic/atheist and even gay conservatives, though they're not a majority. Usually many of our viewpoints can either be far left or right, or you're somewhere in between and/or lean more towards one side. It's not a two-sided coin subject at all. Usually when people have a mix of viewpoints and identification for certain stances, they're not completely all at one end of their political spectrum to begin with.
So anyway, if you consider yourself as liberal then only you can determine that. If you agree with one side more so than the other then you'll probably fit under that section or group of people. We can't tell you as to how you think and what you identify as. I don't agree with a lot of liberalism/progressive agendas even though I'm not a religious conservative. I go with libertarian and Constitutional with limited government standpoints, respectively, which can take some form of conservatism or maybe even a hint of classic Liberalism (look that up if you don't know what it means.)
