Hey, I have come here from kyriakos post and skimmed over your article.
You are still making some shaky assertions yourself.
Like the assertion in your question '..disgust towards homosexuality only exists among a small portion of the human..' .Disgust of gays may exist in most of the population but some perhaps grow out of it before puberty due to culture ,better prefrontal functioning etc..
My knowledge of biology is fairly limited but I am wondering of why do such things need an evolutionary usefulness ? Isn't it possible for them to happen as a faulty byproduct of otherwise good genes e.g by the wrong genetic combination like if gene R is combined with gene T they produce a homosexual while in every other combination R and T produce some other trait that may be useful .
Anyway I would like to ask you something else since you seem to be fairly intelligent . Is it true that the payment for the average article in steem has has been dropping for the last 2-3 years?
I am thinking of writing some articles myself in this site.
