Republicans, dogmatic Christians and folks without much post high school education typically say "yes - being gay is a choice".
They give this answer because the alternative answer is unacceptable - that being: some people are born gay, and thus they are made that way by God.
Why Won't God Heal Amputees?
Before this whole "gay" lifestyle thing became a fad, Most doctors, phychiatrists, and educators were very much of the opinion that homosexuality was an abnormality --- an outward manifestation of a dysfunctional individual.
Some people murder. Would you blame God for that action? Have you never wanted to kill someone? However, the responsible person sees that such a thing is not what God would have one do........... Sex is not the end all of emotional love. Christ died on the cross for our sins because He first loved us. This perfect example never involved sex. It involved commitment. A mother doesn't face labor to have a baby because she's a sadist. She does it because she loves the baby she has been carrying around for months.....
The popular acceptance of homosexuality is turning everything inside out. And what was once considered very sound moral judgment is now cast aside as though it never existed. Good is now bad and bad is accepted as good. But the end results have not been shown to be any less valid.
