No. Nothing is refuted. Being left handed or right handed simply doesn't affect anything even remotely significant.
You should have said that before posting some tripe about learned behaviour, then.

That's my point. Homosexuality appears in nature. It cannot be bread out since it's not an inherative trait.
Geneticdamage accures quite often thouhg.
It's too frequent to be simple random mutation, so what specific damage or factor could possibly affect a multitude of animals in such a specific manner? As far as I can tell, you're suggesting not only some mysterious damage occurs, but that it occurs with exactly the same symptoms and effect in (for the example of sheep) 6-10% of Rams.
One would almost thing such a thing was guided if it was true.

On the oter hand, as some of you here said, animals don't have the emotional or especially mental complexity of us humans.
And homosexuality still appears by creatures with the brains the size of peas.
If it were the product of complex effects from our sorroundings (upbringing) why would then animals be so affected too?
Now, this is where you aren't really making sense. Firstly, homosexuality in animals doesn't preclude that gene being spread, as it is most likely recessive. i.e. a homosexual animal could be born to 2 heterosexual animals.
Secondly, as you pointed out, humans are substantially more mentally complex than animals. That means it does not follow that the cause of homosexuality within animals must be the same as for humans. You could indeed say the complexity of human intelligence and behaviour actually makes it more likely for homosexuality to be introduced by environment.
You will note, no doubt, that this does not rule out a genetic pre-disposition. AFAIK most scientific studies have concluded human sexuality is a mixture of genetics and environment.

So when a man is born with 6 fingers and it doesn't hamper him at least. you still wouldn't say it was mutation/genetic damaged - that he is "damaged" in some way?
Sorry? What on earth is this in relation to? If someones born with 6 fingers, then no, they aren't damaged in any way. They are different.
Hell, depending on the dexterity of that extra finger, they might be
better.

No they don't. 1 man + 1 woman. Homosexuality doesn't prevent heterosexual sex being physically possible, as should be evident. I believe there are numerous cases, for example, of lesbian couples enlisting a gay male to assist in procreation.
Of course, by that reckoning all technology is a step backwards. It' worth noting that evolution is not just a physical but behavioural process, thus including the impact of technology and society.

I don't know about that.. We humans are stunningly diverse yet we have been living motly monogamus for a long time.
besides a smalelr family ensures more focus and care on the offspring. and mroe resources spanetn on each offspring.
Um, that's not really true. Polygamy was probably more common in the ancient world than monogamy. It was practiced in ancient Persia, ancient India, the modern and ancient Islamic world, Asia , China (i.e. concubines), tribal Africa and North America. When the Romans were beginning to advocate a monogamous society, it was very much against the trend of the time; and even then the men were given unrestricted access to their female slaves.
EDIT; the latter is credited with being the cause for addition of monogamy into the bible, at the time of Paul IIRC.
The ethnographic atlas (
http://eclectic.ss.uci.edu/~drwhite/worldcul/Codebook4EthnoAtlas.pdf, page 4) lists more societies as being at least partially polygamous than as monogamous. (see also
http://lucy.ukc.ac.uk/cgi-bin/uncgi/Ethnoatlas/atlas.vopts)
Whilst it's true that having a monogamous relationship might allow focusing of relationships, that's ignoring the problem of infant death; in ancient times when childbirth was risky, it was essential to maximise the prospects of having offspring (for example). Also the status symbol value of having multiple wives in, say, tribal societies.
