Well, I’m sorry for the autistic people who live like that, it was mainly for the people who simply refuse to grow up.
There's nothing wrong with someone still enjoying cartoons, even as an adult. Especially from their own childhood.
I still enjoy all the old Cartoon Network, Nick, and Disney shows I watched as a kid, such as Dexter's Lab, Ed, Edd, and Eddy, Courage the Cowardly Dog, Johnny Bravo, Cow and Chicken, Flintstones, Scooby-Doo Where Are You, The Jetsons, Hey Arnold, Rocket Power, Danny Phantom, Goof Troop, Swat Kats, Batman The Animated Series, Digimon, Pokemon, Reboot, Samurai Jack, original Teen Titans, X-Men Evolution, and so much more.
That doesn't necessarily mean a person is refusing to grow up, if that's what you're trying to imply here. Personally I never got into "YouTube Poops", which was very much came after my childhood, and I don't know what you're considering as children's food in this list, but that seems like an odd take on it? Maybe you can elaborate more on this.
But regardless, I'm happy with my shows along with things like Home Improvement, The Bing Bang Theory, Rosanne, Everybody Loves Raymond, Full House, and similar from that era. Of course I also have my select anime, between Dragon Ball Z, Dragon Ball Kai, Tenchi Muyo, My Hero Academia, and etc.
