The argument that being intersex is a “biological mistake” or that nature made a mistake or that mutations are genetic mistakes or whatever is so incredibly stupid if you actually understand how evolution works. Aside from the fact that trying to use the appeal to nature fallacy about a natural event or process is incredibly stupid, mutations are supposed to happen. If we’re personifying nature here, nature wants them to happen. Mutation is what allows for evolution to happen. Yes, mutations can have negative consequences (or no consequences at all, or a mix of positive and negative consequences: for instance, the gene that causes sickle cell anemia is protective against malaria when a person is heterozygous for it. Yes, there are things that having CAIS increases my risk for, but I also am naturally less likely to get acne, for instance) but that’s what’s supposed to happen, evolutionarily speaking, because evolution is just about throwing mutations at the wall randomly and seeing what sticks. The genetic mutation that causes my intersex variation is a result of the most natural process there is. And also, mutations are what cause genetic diversity, which is incredibly important for the health of a population. People being intersex is nature working as intended.
