I'm not saying that's not possible. I'm just asking because I see so many more gay atheists around here than gay theists.
Personal experience is rarely objective or diverse.
In a way it reminds me of that old saying, "The squeaky wheel gets the grease."
That is... What are you seeing? What are you looking for? If 50% of the people on this forum were atheist and gay and 50% of the people you met in your life were atheist and gay would you presume that statistic is true?
Then beyond that even. How carefully are you keeping track of what you see in terms of atheists and gays around here? Is there an excel spreadsheet with rainbow flags, upside down crosses, dawkin lovers, pro-hetero folk, loves puppies etc.
How would your personal experience rank against your neighbors and whose is more valid?
But what if you had an objective study. In an objective study about something so personal it is universally known that most people prefer to keep their so called deviant sexual behavior in the closet then how accurate are the results? (Granted a study that attempted to link Atheism as causing Homosexuality would probably only be acceptable in a loony tunes world of reality and I am fairly sure your not knocking on that door.)
Where I think you are going is does Christian teachings of proper sexual behaviors cause people to leave the faith and pursue a more rational option?
The answer is sometimes. (IMHO)
Why? Well the ideas behind what is proper sexual orientation and the teachings of what is right and wrong can touch a nerve for someone who feels strongly that something they feel is right is being characterized as sinful and wrong.
That is more plainly put, someone can feel VERY strongly about these two issues. (And other issues as I have discussed before but to stay on point here) Imagine you are raised religious, love going to church and dressing up and seeing your friends. You love bible class and the exciting stories of the ark, parting of the seas and just everything to do with god and jesus just makes you happy. Puberty comes around and your friends are sleeping over and you realize that you have feelings for one of your friends and they are the same sex. These are strong feelings and you notice similar feelings but only around people of your same same sex. You go to church one sunday and you hear how wrong and sinful and evil it is. Most people don't care because they don't feel that way. But some do care.
Some care because they don't think homosexuality is wrong and think the church is wrong and can easily divorce themselves of the church to do what they think is right. If the church was wrong about this then what else are they wrong about. Atleast they have some in roads for breaking indoctrination and embracing the genesis of skepticism.
Some care more about the church and perception and try to repress their nature and never tell anyone how they feel and to live their lives as the church states they should.
Some care more about the church but seek help for their feelings and go through various stages of counseling or confessions or private meetings and some overcome their nature. Most don't.
Some care more about their own personal beliefs and if the church disagrees with them they find a christian religion that allows homosexuality.
Some care more about perception and how their community views them and get a farce wedding while leading alternate lives.
The list goes on.....
But there is also the people who aren't gay who embrace homosexuality as deviant, sinful and evil behavior and they care. They care so much they drag people behind trucks, make fun of gay people at school, throw rocks, break windows of any car with any type of gay symbolism or engage in other harmful, hurtful and destructive behavior.
Some care more about the homosexual issue and think the church is wrong and similar to above begin to question the church on other matters.
Some care that the message their sending is hurtful to their kids and are unsure if their kids are gay or not but would never willfully subject their kids to harm.
Some care that their friends are gay and they feel they are mocking or not supporting them by going to church... etc.
And the list goes on....
Bottom line... Why does the church teach Homosexuality is wrong and do they have proof? No they have a devout blind faith and teach devotion to it with the unsubstantiated reward of afterlife goodies. (The equivalent of me selling you the rights to a toll booth of bridge I own in brooklyn). Regardless of why they teach its wrong is the teaching that is wrong doing harm? Yes? So why keep doing it? The infallible bible... Kill your kids if they talk back or dishonor you, don't eat shrimp and gay people are bad. They read and practice whatever they want. Pick and choose ministries - ostracizing and judging people based on the words of wisdom written by ancient people who thought the earth was flat and sickness and disease were infestations of demons that could be cured by priests instead of doctors. Societies of people who crucified humans and embraced slavery and torture. All that crap they got wrong but the bible... gold baby...
Yawn.
