You are completely right about Steven Universe's viewership. I babysit quite a bit, for extended periods of time. The kids never want to watch Steven Universe, asking me to turn the channel or put on Gravity Falls instead. I've asked them why, and they always say that they don't get it or that it is boring. They love Gravity Falls because of the fantasy elements and the humor. While the show was airing, I'd help them decipher the codes at the end of episodes and they would start theorizing and playing as the characters. Kids aren't stupid, they aren't falling for the progressive brainwashing because it's not written for children. It's written with progressives in mind, and kids see straight through that shit.
