I can summarise this comment:

1. You personally believe you have some magical ability to sense someone's karyotype, and that you can definitively say that every person you presumed to be cis, actually was.

2. "This didn't exist when I transitioned, so you shouldn't have it any different to me". Which is a vile concept.

Congratulations. You transitioned when it was harder to do so. Are we supposed to surrender progress in order to keep your sense of historical proportion happy?
