How much is religion a part of your culture?

The short answer is that there is no culture without some form of religion. As for my country and my day to day life, I can't separate my experience as an American from Christianity ideologically speaking because so much of American culture owes it's existence to Christianity from an ideological standpoint.

Unfortunately many people seem to be completely ignorant of this, for instance the concept of innocent until proven guilty, the concept of inalienable rights etc. I say it's unfortunate because people tend to be like water in that they naturally seek the lowest ground of understanding because it's easier to get there but by doing so often end up in a puddle mistaking it for the ocean.
