Interesting word, 'malfunction.'
Even if it did not require two sexes to reproduce, even if reproduction were not a common end, indeed part of the definition, of all life (from a material point of view), even if there weren't potential health risks to anal sex that don't exist with vaginal sex, every culture on the planet is heterosexual. If not a biological malfunction, homoerotic attractions are a social malfunction.
Suppose we had the technology to "change someone's orientation" without harming them in any way. No other aspect of their personality, physical health, etc, would be touched. Does anyone doubt that people so changed would fit into our society better and be happier? Of course not. Encouraging gays to think they are normal, and asking our society to adapt to them, is like trying to put a square peg in a round hole.
One or the other will be hurt.
Or more likely both.
Shalom.
The problem here, is the homosexuals are NOT asking. They have come not merely out of the closet, but out of the bedroom and into the street, getting in your face and demanding acceptance.
"You will accept us!" they yell. "Or you are a bigot!"
They refuse to give anyone an option, especially those who respectfully disagree with their behavior.
