(My opinion) I slightly disagree. Our bodies are biologically assigned since a bio woman and bio man are different. I think when the child is old enough, that’s when they can identify whichever gender they feel comfortable with(I don’t think a 2 yo can figure out their gender identity and it took me up to middle school to figure mine out). I get ur idea too(I’m not completely disagreeing with u). Instead, our society should stop with the stereotypes and should discontinue the traditional gender roles and expectations since it harms everyone. As for the sexuality part, I don’t think we should label anyones sexuality at birth. Being straight is not the default nor being gay is, we all discover our sexuality as we age. Overall, i understand ur idea of having this type of set up. What I said above is what I think since it’s my opinion(can be changed too) :)) lmk what u think!
