I've changed the word 'ill' to 'disordered'.
Which, Spud, is just as bad!
Let's face it - the blame for homosexuality is firmly to be laid at the door of your God.
He, in your belief, created men and women in the form which they exist upon this earth. He gave the male a penis which is shaped to penetrate a vagina. He then makes the practice of placing the penis in the vagina one of the most pleasurable pursuits known to man and woman so that they will do it as often as possible to provide Him with a never-ending stream of new followers.
Then what does he do? He says men and women can only enjoy the pleasures which he has thus provided if they want children. Talk about bloody silly! It is not going to take long for someone to invent a way of having the fun without the kids. When they do so your stupid God says that the invention must not be used and some idiot followers of your God are still enforcing this ban despite the over-population it has caused and is causing in some of the poorer countries (Catholic countries most of them) in the world. He also bans masturbation which is probably the oldest form of birth control.
Add into the mix Satan; Satan whom God has put on Earth to test the faith of humanity. Satan tells man that he should enjoy sex as much as he can during his life. God tell man that if he does so he wil burn in Hell after he dies for doing what Satan says and not what he says. Man listens and says "Bugger that! I'll enjoy sex as much as I can while I'm alive - I'll take my chances on what happens after I die.
So far so good - but he also creates man with a penis that is idealy shaped to penetrate a rectum. What happens? Men and women get their heads together - babies come from the vagina - shit comes from the rectum, but hey, it's easier to wash shit off your penis than try to feed a swarm of kids.
Later some men discover that, actually, it can also be fun to have a penis pushed into his rectum.
Don't go telling homosexiuals that they are "sick" or "disordered" - go and tell your God that he made one Hell of a cockup (no pun intended) when he made sex enjoyable and then expected humans not to enjoy it!
All in all - what a wanker your God is!
