Genuine concern and consideration for another human being? And I disagree heavily with the idea that different opinions lays any sort of a setup for slavery, people disagree all the time; it's a side effect of humanity in a world that's rapidly starting to see cultural integrations on a level never before thought-of.

I've always made the statement that I am an atheist until proven otherwise; don't confuse that with agnosticism, it means I do not see sufficient proof (or reason for that matter) to believe in a deity of which man should worship and this is a stance that I wont change until sufficient proof presents itself.
