1) I am an atheist/buddhist myself. I don't believe the evidence for a god has ever been sufficiently presented, though I would find it fascinating if I were proven wrong. I also believe in many of the teachings of Buddhism, which don't inherently require a belief in the supernatural. I do think its possible we may yet discover evidence of, if not a god, some guiding force to the universe. However, I also think its entirely possible that we won't. As such, I feel it would be premature to commit my life to either extreme.
I respect anyone's choice to believe anything they want, whether its nothing at all, something mainstream like Christianity, or something... not so mainstream, like Wiccan. Yes, even Scientology.
I am not so respectful towards religious beliefs that harm or endanger others, whether physically, mentally or emotionally; or those who chose to force their religious beliefs down the throats of others.
2) I think animal testing is a necessary evil, at least until we manage to find a viable alternative, such as perfecting, or at least improving computer simulation technology.
Human testing, if unsafe, sort of defeats the purpose to a degree. Granted killing a few to save the many, if there is absolutely no alternative is a moral grey area.
I support gay rights rather militantly if I do say so myself :U I'm pansexual, so.... yeah. If I want to be with a guy, I don't think anyone has the right to tell me otherwise.
I have a sort of Native American view on hunting. So long as you only kill what you need, and are respectful to the animals you kill, it's fine by me. With the advent of synthetic materials for clothing, I believe hunting for fur is wrong, and whaling is wrong as it threatens to drive them into extinction.
Drinking is only wrong, in my opinion, if it makes you a bad person. I drink regularly, but I know my limits, and I don't get 'drunk' except for rare occasions.
I agree that racism is wrong, as well as any other type of hate based on surface elements of a person, rather than on the quality of their character.
I think a cluster of cells isn't a person, and while I don't think abortions should be done lightly, I believe they should always be an option.
3) Basically, I view life in a fairly Buddhist manner. At its core, life is suffering, and that suffering comes from our attachment to fleeting things and our expectations of what life SHOULD be, as opposed to realistically accepting what it is. We attempt to impose our own views of how life should be on the reality around us, and they inevitably come crashing down and lead to suffering.
I'm also a Nihilist in many ways, and I believe there are very few intrinsic values in life. Morality and the purpose of life are what we make them.
On a related note, I'm also a consequentialist and a utilitarian. I believe what's important is what happens as a result of our actions, and that the ideal course of action is the one that minimizes suffering while maximizing happiness. I believe that its frankly quite foolish to assert that anything is immoral without showing evidence of the harm it causes.
I realize I probably blurred the three topics a bit, but... well, Religion, Ethics and Life are pretty inter-related topics
