Ake & GfS.....

People of all sorts often pursue behavior that is dangerous or generally unhealthy! People overeat until they are morbidly obese: they smoke cigarettes, they drink way too much alcohol, they drive too fast (sometime after drinking too much), they climb cliff faces with no ropes...etc...
   But you seem to be putting sexual practices/inclinations into a separate category....and if I am reading between the lines correctly, you 'seem' to imply that homosexuality would be 'wrong' somehow, even if there were NO dangers involved!

*IF*, Ake, you really mean "The only prejudice I have is against death and suffering, and letting things go on as they are..", then all you should be concerned with is education about dangers, research into cures for HIV and counseling about **safe** sex...etc.; just like education about obesity, smoking, venereal diseases in general and alcoholism.

Sexuality is as powerful a force as there is: research done on monkeys showed that when electrodes were implanted which allowed the monkeys to stimulate the area of the brain controlling sexual pleasure, they would often forgo food in order to push the pleasure button!
We see heterosexuals also take chances, or just 'forget' to use reasonable care when desires drive them, and it is not really clear yet exactly why some people have better control than others. We DO know that in males, testosterone levels can be involved, and other hormone levels control a lot of sexual orientation.... we KNOW this, but you seem to wish to either deny this or ignore it as you cite 'statistics' in some attempt to paint homosexuality as 'chosen' and 'offensive'..(whether you use those words or not!)

People are different!! They don't all like the same kind of cake, they don't all like the same music, and they don't all have the same sexual orientation as YOU. There is more & more evidence that much of ALL orientations in life are influenced by brain chemistry and heredity. Why shrug about cake & music and fret about sex?

IF health is really all you care about, go volunteer to help with educational programs and donate to scientific reasearch!
