Any of those aspects would help, although I feel foolish for asking. I don't have that kind of healthcare knowledge currently. It does get very frustrating when members interpret the scriptures to make it not a sin, so any general help on that would be greatly appreciated. Anything science-wise that can help in countering the pro-homosexuality arguments would help, if valid. You don't have to if you don't want to; mainly, I need more knowledge on these topics.
Are you wanting sources that comment on the ethical/philosophical aspect of these things or just data? Personally, most of my knowledge on abortion comes from working in healthcare and studying fetal development, fertility, and human genetics in college as a molecular biology major. I don't really have a source for it but I can try and find one and share it with you. As far as gay marriage goes, I support it as a legal contract but I still view homosexuality as Biblically sinful, that's how I interpret scripture. I have found most interpretations that say homosexuality isn't a sin are typically not done objectively and with the goal of vindicating homosexual behavior with the Bible.
I have a question, Digsbe. I've been looking to supplement my knowledge on the homosexuality/abortion issues. If you'd point me out to some good sources, I'd reaalyy appreciate it.
