Homosexuality

I was talking to my brother about this topic and did a pretty bad job at arguing against homosexual actions. I am going to write this out before I present my reasoning to him.

Most people would accept that sex with animals is wrong. We know that the natural sex partner for a human is another human. Most people would also accept that sex between a father and daughter is wrong. Thus, we know that sex is not for just any two humans. If someone can legitimately believe these things than it is also legitimate to believe that the natural sex partner for a man is a woman, and for a woman a man.

Additionally, the male and female sex organs are complimentary along with the male and female gametes that produce offspring. Procreation and bonding are both end results of sex; this is the purpose of the sex organs. Homosexual activities use the sex organs in a way that is contrary to their purpose in order to obtain pleasure. In contrast, a person may eat excessive amounts of candy and throw it up later to avoid the effects of eating that food. In this situation, the person is still using their body in a way that is contrary to its purpose in order to gain pleasure. Many people would view it as immoral to eat an excessive amount of food just for pleasure and then throw it up. Thus, it is legitimate to say that homosexual acts are immoral.
