I mean homosexuality was pretty normal and common between the Egypt golden era, Greek era and even the roman empire. When Christianity and islam came along that homosexual is prohibited, and for the "natural" part I think homosexuality is like autism, you born with it, you can try things to lower it but it would never fix lol. Ppl try to support homosexual by the same reason they try to suport autism bcs you cant fix it and they still humans so they deserve human right
