Yes, there are such things as intersex animals, and I can see why you believe that because of them, the idea of sex is on a sliding scale. However, that's where your beliefs fall short. Sex is biological while gender is psychological. An animal that can change its sex does not prove that the are more than 2 genders. While for these animals, biological sex is on a sliding scale between male and female. I put that post out as kind of a joke because my teacher showed us a karyotype of a hermophrodite and tried to prove that there are hundreds of genders because there is someone that biologicaly has both of them. It is people like you who take these things too seriously and it gets out of hand.
