100% correct.. a 9 year old boy doesn’t know shxt about being a fag unless people i.e. parents more than likely pushed that on him.
The mother probably did talk about it with him and perhaps even pushed him in that direction, but 9 year olds get called that every day, and they do worry about it. They know they are being insulted, even if they don’t know the details.
Regardless of what the kid thinks he is, sexualizing children is a perverted thing to do in itself, let alone sexualizing them in a deviant way.
