The Pluralistic Christian in a Pluralistic Society

What do you do when you find yourself in the following cultural situation? You live in a modern western, nation in which the great majority of its citizens claim to be Christians, yet the basics of Christianity is mostly misunderstood, or the pervading attitude towards the challenging Christian teachings is a form of apathy, or complacence? What do you do when you find yourself trying to follow the teachings of Jesus by reading the Bible, and most of your peers application of the Bible is to change nothing, except don't drink, get divorced, hang out with bad people, watch unbiblical movies, or say dirty words, but by all means support war, be rude to liberals, listen to Toby Keith curse and womanize, and make fun of sinners.
(I realize that many of my readers are sensitive to my implications. I am not talking about you. And I realize that I am misrepresenting a whole lot of individuals who are socially conservative, but also very cordial, polite and loving. Please realize that I am being slightly facetious, and that I in no way intend to ostracize my conservative brothers or sisters or make them look ridiculous. I am expressing however a common sentiment among more liberally minded Christians, and this is going somewhere. I don't wish to upset anyone.)
As Christians, we're called to be different; not different for the sake of different, but different in a way that is redemptive. But what does "different" look like in a pluralistic/secular/christian culture. It sure doesn't look like being a homophobic, pragmatist, elitist who doesn't drink or watch bad movies or a drinking, porn-watching, populist, who volunteers at soup kitchens, and pays more for gas effective cars. Why can't someone be a Christian who dislikes capitalism, because they believe it's about marginalizing people, more than helping them? Or be green, or a vegetarian, or vote yes for socialized health care? (Or not?) But who also hates pornography, abortion, and alcoholism? Why can't all of these qualities exist in one human without it being contradictory? What if its exactly what the Bible intends a Christian to look like within a pluralistic culture? What if "Biblical" in a pluralistic culture looks like each subculture appearing pluralistic? What I mean is that the culture is pluralistic in that many worldviews are accepted by the culture at large, but once people find others who agree with them, they form subcultures that are not at all pluralistic. This explains how subcultures become the authority of Christians' lives, instead of the Bible. This explains how the Bible gets re-interpreted in light of the subculture instead of the Bible shaping the opinions of the one individual. But I am convinced that if we interpreted the Bible before filtering it through our culture, that we would produce a truly pluralistic subculture, and that this subculture would be truly counter-cultural, and being that it would be biblically based, redemptive.
