Also, handedness does affect behavior, such as how a person writes. By your logic left-handed behavior is not normal and so left-handed people must be sick.

Ahhh! Stay away you lefties! 
No. Being right handed or left handed doesn't realyl change a thing.
Being gay is actually rather "unnatural" (as in - not good for your species as a whole despite it accurring in nature. Mutations/defecta are common in nature...but animals with those usually die rather fast..
A not must be taken to differ between homosexuality and homosexual behaviour. Is it a sin?
Well, actually being gay? If it's genetic then no. If it's not, then probably.
But while anyone can have distinct urges he doesn't have to follow them - the best thing about a humn mind. Any normal man will turn after a goiod looking woman and will of course be tempted to "try her on for size".
buthe can simply say no. So can gay pople.
so there is a difference between feeling such an attraction and actually indulging in it.
Again, you're relying upon a personal definition of what is and is not 'normal'. I'm not sure behaviour can even be categorised within a sense of 'normalcy' due to the inherent abstract nature of it.
If we go back to, for example, ancient Greece*, homosexuality was an accepted, natural part of the society there. It was recorded in the Karma Sutra in India; it's been recorded in Asia, Africa, the Pacific, the Americas and Europe. And in turn acceptance has varied hugely across these regions. To me that doesn't indicate it can be classed in terms of what is normal for a human being, but what a society considers normal. And that's an entirely seperate thing.
So was canibalism considered normal in some societies. Do you propose we accpet it as normal in our own society?
The whole issue here is is there any damage? How do you come to the conclusion that there is none and that they are functioning propoerly?
"It's not damaged, it's just different." Is it?
You seem to define damages as only something that harms oneself of other individuals. So what? If i have a bening tumor that won't kill me or hamper me I am not damaged/sick?
Think about it this way - the basic function of a bilogical life is to grow and reproduce. homosexuals feel no atraction for the opposite sex, thus they are hampered when it comes to reproducing (it's not as easy for them as normal people).
