Using children in any way as content is messed up. Children should not be used to make money on the internet, EVER.
However, there is absolutely nothing wrong with a child being trans at that age, and implication of such is transphobic in itself.
Chat i just need to get this off my chest, so you know the Youtuber named Johnathon Joly or smh? I personally think it's messed up that his child came out at SEVEN, and that he also uses his trans child to farm views.
