I am a Christian (Presbyterian, to be exact) and I do consider some of my politics to be informed by that. Although I fall far short in my faith (as we all do), when it comes to voting I do place significant value on a candidate's level of compassion for the poor and the disadvantaged. Indeed, part of my, generally speaking, liberal views on things like spending and taxation, education, and welfare policies in general are driven by my faith and view of Christianity.
words vs deeds - again I think the fundamental disconnect is your view that conservative policies are less compassionate than liberal ones. It is a matter of how best to address the problem, not whether or not the problem is important. Obama is constantly talking about helping the disadvantaged but his actions don't match - he's dolling out the best to his political allies and under his policies, the plight of the poor has worsened.
So when I see people who look down on me because I'm a liberal, who proclaim superiority based on their Christian values, but then who either run for office or vote for others based on policies that outright promote wealth accumulation and cutting off services to the poor, I guess it just rubs me the wrong way.
