No, it's not as simple as all that. "women and blacks" are states of being since birth. "gays" are part of a behavioral group, a cult movement of some, but not all, deviant sexual behaviors.
Tell me, how could I check to see whether someone was actually a "woman"? Genetics maybe? Is XX female, and XY male?
What if I had on my hands a male but they looked like a woman? What are they really, male or female?
If you had your hands on a man that you were convinced was a woman, what they really would be is "mentally ill", and male of course. If that level of denial of reality of what a person was born with between their legs can lead to such a state of complete delusion and confusion that they would seek the assistance of medical "professionals" to amputate healthy organs and body parts then that soul in that body is so tweaked, so twisted, so disturbed that you should run a thousand miles per hour to the most distant point of the globe of that person.
That's why you see the parody in film on the classic "man discovers the woman he was with was actually a man" leading to the next inevitable scene: projectile vomiting. It's because we are hardwired to recognize perverse and severe mental illness when it slaps us upside the head with a brick like that.
My personal thesis on why we are hardwired in such a way is rabies. Bear with me. The main symptom of this completely 100% fatal zoonotic disease [crosses all warm blooded species] that has been with the animal kingdom for millions of years is an animal clearly acting mentally disturbed. A visceral revulsion for highly disturbing behavior quite likely evolved as hardwired as a survival tool. So actually, properly in this argument, if my thesis is correct, wise "homophobia" is actually the only thing "born that way", while gay behaviors are the result of faulty imprinting at highly suggestable age just on the verge of puberty. Animals acting patently bizarrely are always ostracized from the herd with good reason.
