No, this isn't about sexual "orientation", which in a purely clinical sense only pertains to whether one is male or female. No, this is about sexual behavior, which is absolutely a choice. There is nothing innate about such behaviors. One must choose to engage in such acts, it does not happen in the subconscience. The whole "born that way" myth has been astroturfed from the bowells of pseudo-science, wherein correlation DOES equal causation.
The proof is in the fact that many people have successfully changed their addiction to abnormal sexual behaviors. No one can change their race or ethnicity, and despite pop culture ignorance to the contrary, no one can change their gender (which is embedded upon conception) - they can only mutilate themselves to make them appear to be the opposite sex.
Therefore, one's sexual behavioral choices are just like their other lifestyle choices, aka they choose to be a racist or a pedophile or a tranny. Any correlative physical characteristics that may contain statistical alignment with those feelings that can compel such behaviors DO NOT IN ANY WAY FORCE ONE TO ACT UPON THOSE FEELINGS, and therein lies the difference. Otherwise we wouldn't have laws against rape, incest, pedophilia, et al.
Remember also that sex is supposed to be a personal matter, not one for public consumption. You and the rest of your lunatic fringe have no standing to compel someone else to give consent to your sexual liftstyle choice. If they find your particular sexual fetish objectionable, well they have the right to refuse to do business with you.
Equating one's sexual behavior as being akin to a race or ethnicity is nothing short of insanity.
