im simply pointing out humans are a conscious enough species to be aware of their imperfections and what they can lead to. even if those imperfections come from how we've evolved
I'm still not sure of the point you're trying to get across. Humans are sapient, animals are not. A consciousness of evolution is not apparent in either, and if evolution were conscious (which it would need to be for it to be a possible explanation for life at all), it's doing a terrible job considering that the majority of mutations are imperfections.
And since humans are conscious enough to be aware of their imperfections and what they can lead to, then there would be more reason to avoid homoloveuality for the sake of self-preservation.
