If you want me to stay on topic then you stay on topic and cease making accusations you cannot backup with facts. You brought up polygomy and make a broad statement that is blantently false concerning polygomy and Christianity. I simply showed that you are incorrect.
I do not deny that the fastest growing segment of the population to become infected with HIV is heterosexual women with African American women leading this group. However the infection rate among gay men remains at about 50% of all new cases in the United States. Now since only about 2.8% of our adult population is gay what does this indicate?
And once again you are not reading my posts with any real discernment. The CDC, which tracks national stats on STD's has stated gay men are from 5 to 5000 at greater risk of infection; the CDC does not state heterosexuals do not contract STD's.
You comment concerning vaginal cancer is laughable since men don't have vaginas; yet all human beings have an anus. Also what you are ignoring concerning the Netherlands study is this study was done in a gay friendly country where gay unions are legal therefore once again you are side stepping reality.
As to environment, even secular scientists and psychiatrist state one cause of homosexuality is the result of environment so you are helping me make my case.
