Depends on where you are really,
In a factual sense yes, homosexuals are unatural. The survival of human beings relies on natural sexual reproduction aka X+Y/man and women go bang, bang, etc., etc.
But nothing's wrong with a homosexual...socially. Some collegues believe it to be a genetic disposition or a hell-worthy trespass.
I don't WANT to think it a personal choice. Down with the hate!!!
They're just part of the world at large, it takes all kinds for me to be politically correct to quote "Differen' strokes fo' differen' folks."
Regardless of any underlying cause, to call them out as queer or destructive takes as far back as being a racist or a purist. I won't beat down someone for their sexual preferences or lack thereof to decimate the centuries of human progression.
