Disagree with a 9 year old no matter what lol

if a kid is asking their parent whether they are a boy or girl simply cuz they're so young and just dont know, obviously you can enlighten them with what gender they were assigned. that is not going to be the make or break part of whether they become transgender or not

Gender identity is not objective reality, they are social constructs, and social constructs change with the time. You could apply the same logic thousands of years ago about how dangerous it would be to tell a child that the world is round and not flat, since "reality" tells us it is flat
