This would be like saying you are gay, its not your choice, you HAVE to be this way, its just how you were born... or worse for those who disapprove, you are defective.
If you look at it strictly from an evolutionary point of view, you could claim that.
But then people who suffer from a mental illness, obesity, deformation, not having perfect looks or physique, hereditary illnesses, infertility and many more are all
defective as well.
The whole Y chromosome could be considered defective since it's a lot shorter then the X chromosome and therefore a lot more susceptible to corruption for cell division.
Evidence has been found to support both the fact that it's based on genes and that there is some degree of flexibility on sexual preference within someone's lifetime, more so with women then with men (as per that particular study, I'm not stating it as a fact).
Whichever the case may be, I do believe that it's not a choice you can consciously make. You can't will yourself to suddenly be attracted to a certain sex, you just are or you aren't.
A lot, if not most of the sex we as a species engage in, is not meant for procreation so we're all
unnatural in that sense.
Like Robert also pointed out, the simplified basic issue is whether or not homosexuals should have the same rights as heterosexuals or not.
On the whole "give an inch, take a mile" point of view. A close related demand is adoption rights for a homosexual couple. In Holland both same sex marriages and adoption rights for same sex couples was made legal. In Belgium it was only same sex marriages and adoption rights is still on the table.
It doesn't have to be everything at once, but it should at the least move forward.
I don't live in the US so my view on it may be warped, but it seems everything has to be overdramatised. Neither Holland or Belgium saw mass protests of outraged people or mass political protest. Nor were there thousands of same sex couples rushing towards city hall to get married.
