No kid would get this idea on his own unless it were sold to him through the communist education camps.
And some loony attention seeking parents. I’m just surprised they “let” him “go back.”
It's perfectly normal for kids to get ideas like that.
I had kids who decided they were a puppy, a fire truck, and a space alien, among other things. What's abnormal is for parents to take a small child seriously and demand surgery . . . and then demand that others play along.
Given all the hatred of men, the war against boys, it isn’t unreasonable that some boys try to “convert” to anything else to gain approval. And transgenderism is applauded, celebrated, right now.
I suspect the sizable minority of millenials who say they are bisexual is also a symptom of this, to say “You can’t hate me as a straight white man, I’m bisexual, a sexual minority”.
