nah bro seriously the third gender is like the most regular in 4-9 yro boys always thinks that they are better than girls and girls always thinks that they are better than boys. Atleast in my country if not in yours.
Since most children that has not hit puberty [yet] do not feel any sexual attraction towards others, it should make them asexual, therefore children who haven't hit puberty [yet] are apart of the LGBTQIA+ community.
