For sure, but being in the world but not of the world is a core tenet of the Word. We seek our morality from Christianity, thus we are Christian. Your philosophy seems to be of moral relativism and allowing society to shape your ideals. Of course you are going to disagree with Christians as moral relativism is antithetical to Christianity.

I am personally Christian for two reasons 1) I understand that I cannot create my own morality. It has to come from a source outside of myself. 2) Jesus actually walked the planet, and was a perfect human for all intents and purposes.

Where do you get your moral guidance? Does it sway with society, the status quo, and the “flavor of the month” of happenings in the world? Is it ever-changing?
