Some people try to claim that being gay is a choice. It generally isn't you are attracted to who you are attracted.
I'm a hetero woman. The thought of having sex with another woman is nauseating to me. This isn't a "choice" it's what my biology dictates to me.
Some people are bi-sexual and the argument of choice could be made in their case.
Most homosexuals are not bi-sexual.
Being a homosexual is perfectly natural. The rise in homosexuality in societies today has nothing to do with "sin". Animal populations that grow beyond the carrying capacity of their environment start to produce more homosexual animals. Homosexuality is natures way of telling us that our population is too large and we need to cut back. I don't know what the exact triggers are. It could be pollution based. But we have changed our environment and created triggers that have increased the homosexual population in an attempt to lower our population.
We should be grateful for the gays. They are helping us reduce our population to manageable numbers.
Thank you to the gays and lesbians around the world.
