Quote from 420Ace DrakeThat was exactly my point. NOW we have the techonolgy, but before 100 years we didn't. If everyone was gay or lesbian it would've been the end for our race. No matter what say, feeling a lust as a male for male or as a female for female, is a brain malfunction. If it was natural, why didn't we evolve with both female and male organs?
I don't know enough about homosexuality to say whether literally is a "brain malfunction," but in this context "brain malfunction" = "mutation," and mutation is and has always been a natural way of life that drives the force of natural selection and happens constantly in our world. Without mutation, many organisms, including humans, wouldn't be where they were today. Besides, evolution isn't perfect, it's more or less an editing system, so using it as justification to show that something isn't right is silly in the first place.
I'm confused about your argument. If you're arguing that homosexuality is wrong and shouldn't happen because it isn't natural, then https://yourlogicalfallacyis.com/appeal-to-nature
If you're simply trying to factually state that homosexuality is a "brain malfunction," then you need to actually provide proof and evidence instead of asking us to prove you wrong.
