I will answer each of your points.
1) It is not clear from your scripture that "homosexual sex is a sin." Different people interpret in different ways the few passages of scripture that may or may not address this topic. Since I do not adhere to the Bible as an authority, I have no position on what its says. I don't follow the Bible, and arguments over what the Bible says are meaningless to me.
It is abundantly clear from scripture that fornication is sin. Fornication, the word Jesus used includes: any kind of illicit sexual act, which includes: Adultery, premarital sex, homosexual sex, and sex with other species. In other words sexual conduct that is outside the realm of man and wife (wife being a female).
2) God has given people no "guidelines" for sex, in my view. The Bible was not written by God, nor was it inspired by God, in my view. I reject your premise.
Well, that's fine. You are at liberty to disagree. My question is then. Why are you debating this issue with people who believe in the scripture as the inspired word of God?
It doesn't make sense that you'd try and convince a Christian that fornication is acceptable to God when, our text repeatedly says over and over that it is not.
You appear to believe that "God's guidelines" require sex between a man and a woman in a monogamous marriage. You suggest that any sex outside of this kind of relationship produces disease (you probably mean spreads disease). That's simply not true. Sex between two women almost never spreads STDs, as someone else has already pointed out.
This is not true. From what I've read the studies are very small partially because Lesbians are not inclined to be checked regularly. Regardless "almost never" is not a term I've heard used in any medical report.
Sex between married opposite-sex spouses CAN spread disease. A man who is already infected with an STD can marry a woman, and she can contract the STD from her husband. Married heterosexual spouses contract STDs from each other all the time.
It is fornication which spreads the disease not married heterosexual sex but those who go outside the bounds of marriage either the male or the female.
3) Homosexual sex does not spread disease any more than heterosexual sex spreads disease. Most of the AIDS cases in the world are among heterosexuals. And lesbian sex almost never spreads STDs, as people have pointed out several times. It's not the sexual orientation of the people that spreads disease; it's the specific sexual practices that can spread disease if one of the people involved is infected.
We are discussing fornication which spreads disease in particular we are discussing homosexual sex which absolutely does spread disease more readily then other types when we are referring to anal sex.
4) You have compared gay people to psychopaths. This is as nasty comparison. If someone compared Christians to psychopaths, wouldn't you find this nasty?
No I haven't I was comparing behavioral tendencies. I've even included some of my own. So you could say I've compared homosexuals to myself and my own sinful tendencies. However, that would not be accurate either, my point was because a person may at some point declare "this is the way I am, I have these impulses" to do whatever, that, does not make the impulse right, moral, or acceptable. Acceptable to God, according to Christian belief's that is.
4a) I have already answered your question. Since you apparently didn't read my answer, I will repeat myself.
There are conditions that people are born with (I can't speak for psychopathology, since I don't know enough about it) that are clearly problems for people. People are born with congenital problems all the time. Let's take one that is not so nasty-sounding. Let's take a congenital heart condition. Does God make people with heart conditions? Yes. Is the condition a problem? Often yes. Should we seek to treat the condition if we can? Usually yes. Why? Because the heart condition is a problem for the child, and we want to help the child by getting rid of the problem if we can.
First of all I couldn't agree that God creates any sickness....
Secondly you seem to misunderstand me altogether. If you desire to live a homosexual lifestyle that is up to you. It's frankly none of my business. I'm simply defending my belief's as a Christian and relating the fact that Christianity does not support fornication of any kind. Not even the kind I'd otherwise like to partake in.
Now let's look at being gay. Does God make people gay? Yes. Is this a problem? No. Should we seek to make people somehow become not gay? No. Why? Because being gay is not a problem.
Your God may "make" gay people. However not the God of the bible. He teaches us if we have these desires (any type of fornication) we are to repent and seek His empowerment to live a Holy Life. It's a process we all struggle with sinful desires of many kinds, homosexual desires are just one of many.
