I don't feel like going through your post and pulling out quotes so feel free to refer back to see what I am responding to.

Sex is not required to be healthy. I'm healthy (though my cholesterol is a tad high) and happy and been celibate, by choice, for years. A "need" for sex is not healthy and cause to seek psychological assistance. Sex is fun, so is jumping out of airplanes. Neither are necessary to be "happy" if either is, then you have much deeper problems.

Your statements on not excepting risk are childish. Every time you choose to do something, you accept risk, even if you choose to just sit in your home and do nothing. You may or may not think about what those risks are, and in doing so make an adult decision about if you want to accept the risk and do it anyway. However, the risks are not dependent on your reasoned awareness, they simply are. If you choose to eat raw pork, you are risking becoming ill. If you tap dance across the freeway, you risk becoming a smear on the asphalt. If you have sex (even "protected" sex ), you risk pregnancy and/or STDs. Sorry you don't like it, but that is the way the universe functions, your preferences do not matter.

You are legally allowed to use deadly force to stop a rape, and I urge you to do so. However, you are not legally allowed to shoot your attacker after he pulls his pants up and walks away. Personally i would hunt the scum down and insure that he/or she met an extremely grisly end, but the law doesn't see it that way. This is where your analogy breaks down. Frankly I think execution is the only way to punish rapists, but too many other folks disagree with me, often referring to the "sanctity of life" and how it is wrong for the state to murder someone, or how execution is cruel. Oddly enough, many of those same people are OK with abortion...

I am unable to follow the reasoning on your plant metaphor. The only way I can make any sense out of it is using existential philosophy; but I seriously doubt that is what you intended.

Would you walk out in the morning, an upon finding a cute little kitten snap its neck, or would you go get it a saucer of milk? If you wouldn't kill the kitten out of hand, why do you think it is OK to simply kill a human child? BTW, killing the kitten would get you arrested and jailed, another law that is often supported by folks who are just fine with elective abortion. If your reason for the difference is the amount if inconvenience that child could/would cause you, then I feel sorry for you.

The vast majority of us, seeing a child sitting in the middle of a busy street, believe we would risk our lives to run out into traffic to save him/her. The public at large would cheer that person as a hero for their selfless action. Why is a child that has not yet hat its first taste of oxygen worth less than the one sitting in a burning building?
