arguing against the idea that "bad genetics" are what make bad people

I have never said that genetics are what make bad people. I said that there are two things that can influence a person's behavior, their genetics and their lived encironemnt.

Genetics obviously contribute to a person's behavior and this much is a known scientific fact. You can ignore it all you want but that doesn't make it not true.

as an autistic person, I shouldn't have to explain why I think this is vile.

I fail to see how that's "vile". I haven't looked into autism spectrum disorder but as far as I know it is a mostly genetically defined disorder. But even so, how is that "vile" or "ableist"? I too have disorders I suffer from that I inherited, ie, that I got from my genetics.
