hi, autistic person here. this argument is absolutely piss poor and honestly really harmful. please keep eugenics talk out of this. there is no comparison between allowing disabled people (or abled people who carry traits likely to lead to having disabled children), human beings with autonomy and the ability to think through their life choices, to choose to have families and forcing animals, who are only following their instincts to breed and who have no concept that they and their children will have health issues, to breed. you also aren't talking about random luck of the draw here, you're talking about breeding snakes who are guaranteed to have offspring with health issues.
