There is a difference between “you are egg take hormones now” and “hey, you know that quite literally is an option, right?”

Do say something! Acting like you know someone’s gender better than them is bad, but talking about the possibility of transition to potential eggs is a good thing. There’s so many repressed and miserable trans women out there, that only need some reassurance and help. The “egg prime directive”, in how it’s often interpreted, is actively harmful.
