My honest opinion is that no, it shouldn't be, since kids at that age don't even know what they want to be so it would just confuse them further (no kidding, I wanted to be a werewolf at that age and every time I remember those days I just cringe at myself) It really doesn't need to. People over the age of 18 can do what they want, but before that just let them be kids, because when you keep repeating an idea it gets to indoctrination (be it religion or lgbtq stuff)
