Dude,
Something like 95% of children's entertainment is made specifically for white kids.
My son, like most children, is into marvel characters, all but a handful of which are white.
He loves youtube. Learns a lot of great stuff from it. But again, practically every YouTuber the algorithm picks is white.
Favorite cartoon characters? All but a handful of them are either white or Japanese. Just like his favorite video game characters.
It's the same thing with all of his cousins, classmates, and practically every other child in the city.
His mom and I allow it because shared media experiences is a big part of the way that kids bond with each other. On top of that, we have limited control of what he sees at other people's houses.
Even if we had full control we would literally have to keep him in a box to avoid all of the advertising, promotional tie-ins, and all of the other media which makes this stuff so appealing in the first place.
Yet somehow we're supposed to expect our children to not want to go to a theme park filled with all of their favorite characters?
I'm guessing you don't have kids because that's not the least bit realistic.
