I now see why SJW-driven works take so much inspiration from certain anime like Pokémon and Sailor Moon.
In the former, you saw a literal ten-year-old kid going around the world capturing critters, battling and whatnot. All with the simple motivation of being the best, like no one ever was. I think later on he and his travel buddies started getting entrenched in world-dominating/destroying conspiracies, but the original rarely touched that.
And in the latter, you saw a total loser of a girl suddenly become not only a tremendously powerful warrior, but also the literal Queen of the World, who marries the hottest guy around, gets powers to defeat her enemies at the most convenient time, and also cheats death not once, but twice. More, if you count the movies. All with literally weaponized love, because in case you forgot, it's a shoujo and Japanese girls love those frigging things, it seems. And the author even said a good portion of Usagi's ethos and happenings to her are her own power fantasies at play.
I think Dragon Ball Z also had a similar premise, but aimed at boys, natch. You saw an idiot savant who, possibly due to his Saiyan nature, has only two interests in his life, and those are fighting and becoming stronger, and then get excited for more fights, all at the expense of his family, close friends and the entire world, who are perfectly fine with his simpleton mannerisms. On the very least, you saw Goku and his buds train and bust their bones to achieve their powers, but still. I think there was a discussion about the consequences of Goku being a shit father and husband somewhere in this very thread.
Mind you, those aren't the rule, but are possibly the most popular in their target demographic, at least for Western audiences. I'm not one to bray about "bad examples" but I can't help but see the patterns.
But yeah, the point is that content creators have purely fantasy-fulfilling works as their references. You can't just have Captain Marvel as a woman who must overcome her ego to truly earn her place in the pantheon of heroes. Das sexist! She's perfect and powerful already, so she can do whatever she wants! Oh, a lesbian couple where one of the parts was nothing but an abusive jerk to her, and was more of a wrench to their plans than anything? Fuck that, LESBUNS! Therefore Catra will change her heart, declare her love for Adora in the nick of time, have her crimes forgiven and they live happily ever after! No questions, just consoom and live your fantasy.
Sorry for the long rant.
