there are very likely to be kids out there who not know much about the process of transitioning or gender roles in general and would genuinely perceive themselves as being female instead of male (or the opposite) for whatever reason
the fact that you're saying there's literally no way this could exist is stupid, children are known to be like this. it's like kids saying "i want to be a fire truck" they obviously do, yet we don't make kids transition into fire trucks because that'd be stupid and they probably don't know how that works very well. same thing applies with normal transitioning
