Now that you have exhausted your logic and common sense, why not go to a higher authority and read what God himself says about homosexual behavior and about the sanctity of human life?
For one example, Romans 1:26-27 gives God's view of sex acts between people of the same gender. He calls those acts "vile affection". (vile = evil) Same-sex "marriage" compounds the evil of homosexual behavior by making a perverted mockery of the God-ordained, sacred institution of marriage.
nor can I see how abortions can be nothing more or less than murder. I give up, I'm very confused.
No need for confusion, God's word is quite clear on the matter of killing innocent humans, see Exodus 20:13. Abortion is the deliberate, premeditated killing of a living, innocent human being, and that is essentially the definition of 1st degree murder. God allows for the taking of human life under a very limited number of circumstances such as self defense, national defense in wartime, capital punishment carried out by a legitimate government, and perhaps one or two more circumstances. The deliberate killing of an innocent unborn baby for any reason is not one of those circumstances, therefore it is "nothing more or less than murder". (as is euthanasia BTW)
So you see, there's no need to be confused or to give up. All you need do is accept what God has said concerning those issues as final, absolute, unalterable truth.

While I agree that it is deliberate and premeditated, think of the fetus in a more detailed sense. The fetal brain and central nervous system do not develop and become active until the eighteenth week of pregnancy - now, this varies from one mother to the next, but on average, it is 18 nonetheless - up until then, the fetus is developing towards the stage of viability. Up until the central nervous system initiates the rest of the fetus's biosystems to become active, it is not living in the sense of the word - it. is. not. functioning. Not unless it is still within the uterus and functioning off the mother's systems and unless I'm mistaken, while it's inside one's own body, the owner of said body has command over what to do with it.

Agreed.
Well, except for war. Wartime is justified by people with too swelled an ego and too much megalomania. The one or two other circumstances you stated as God allowing for is to save the mother's life. Not all women can survive a pregnancy to term - illnesses contributing to a very hostile environment for fetal development, inability to carry through labor, etc - and when the C-section is not an option, sorry - no pregnancy.
Before you start on how God will protect those women to save the life of the baby, as you inevitably will, stop there. I'm one of those women. I have a hoste of illnesses that render me unable to carry to term or through labor. I want kids, but can't have them because the child and I will both die. Think of that. Prayer won't help me. Extensive treatment might. God has little to nothing to do with my condition, that's a matter of genetics, medicine and whatever science develops while my bio-clock is alive.
I'm not technically pro-abortion, by the way. Just pro-choice, but with a very stringent limitation thereto. I believe that if it's a last resort only, the option should still exist.

I think that the heterosexual population has succeeded in making that mockery themselves, except in a culture of no personal responsibility, not a single person wishes to acknowledge it. "Till death do us part" has evolved into "Till I find someone I'd like to screw more." Divorce is a mockery on marriage itself; last time I checked, if a couple wasn't ready for marriage, there is no need to actually exhaust money, efforts and nerves and actually throw a wedding. Cheating...geez, I don't even want to think about how many couples cheat. I'll tell you this now, if one spouse cheats, either the couple splits or the other spouse never finds out. My marriage - a heterosexual one, in case anyone here decides to nitpick - is being made into a mockery by children in the bodies of grown adults. Homosexual marriages have little to nothing to do with it.
Homosexuals are also Homo Sapiens. Just because they have sex with the same gender doesn't make them any less human than they are; I don't see how karmic senses of evil ro good can pertain to sexuality in one way or the next. The more of less logical way to see it is, stay out of other people's bedrooms. It's not your concern who does what with whom.

No thanks. All truths are tangible from one person to the next; no two people will interpret the same phrase identically. While the Bible is a nice book for moral outlines, it's just that - a book. And need I remind you that Lot's two daughters also slept with him to have children? Some moral that promotes right there. What happened to people figuring out truth for themselves, or is independent thinking as dead as personal responsibility?
