i call that mental illness, & that illness being gender dysmorphia...
at the very least it's if it's not a mental illness, it's a genetic one bc humans are entirely alone with this entirely theoretical genetic occurrence u mentioned, frankly u make it sound more like a mutation of the brain than u do something normal... i'm just saying, thats the interpretation i get from all this... don't get offended...
like, autism is technically natural; bc it does occur naturally but only in humans & u wouldnt say that is a good thing to has occur, would u? autism isn't a bad thing, having an autistic child isn't a bad thing, gender dysmorphia doesn't has to be stigmatized like autism shouldnt be stigmatized... but it's not good either... still an illness...
🌈 homosexuality however, exists across the animal kingdom & there is conclusive irrefutable data that isn't just theory proving that...
not natural if it only exists in people, & isn't a normal occurrence in people albeit rare, but definitelys nonexistent within the rest of the fellow mammals... abnormal, hence illness...
just call it for wat it is 🤷🏼♀️
