My atheism has no reflections on where I get my morals, except that I put responsibility on myself instead of a "God". We all draw our morals from society, even those who appeal to religion, although you might have the underlying feeling that you should be moral is because of a God. What I mean is this: There are things in modern society that aren't mentioned in the bible (or other religious texts) that require a moral judgment (say firing someone, smoking weed, or choice in clothing, etc). You, being religious, probably make a decision based on your religion, the proverbial "What Would Jesus Do?".
