I'm all for letting biological males live their lives as females if they want (and vice-versa). But this push to pretend it's the exact same on all levels is insane. Biological males will have different medical issues and experiences than biological females. Bio males will never be at risk of pregnancy (unwanted or wanted). Bio males will never experience their first "surprise" period. Won't experience the accompanying cramps. Won't automatically be given the girly version of something, because it's convenient. Be nudged toward "female" play even if they aren't interested. They arent taught early to be wary of adults who are too friendly, because there sick people out there. Thier experience, growing up, is not the same as the female experience.
