Let's just say that, pretty much most of the liberal stereotype...that's me.
Add to that Catholic morals on the value of solidarity (socialized medicine, welfare, free public education, including universitites), unconditional love and tolerance, and minding your own sins instead of other people's (and Catholic acceptance of the theory of evolution).
In general, I see liberalism in general in a much more positive light than conservativism as it exists today. The brand of conservativism that's rampant this days is too selfish and inhumane for my tastes, even if they do share my basic religious values and beliefs.
I feel a lot more comfortable amongst liberal atheists, even when I do believe in God.
