Did you actually watch She Ra? Did you ever get to the part where Adora realizes the royal superweapon is a mistake and works to undermine her destiny wielding it? Did you ever get to the point where the princess that does seek to wield that power ends up fucking everything up for everyone? Did you ever notice that the entire message of the show is to reject power seeking nonsense in favor of living happy and free with those you love? How power will not make you happy but loving your gay friend will?
Also, how pacifism doesn't work against violent invaders; that happens fairly early on. She Ra deeply questions the entire concept of the show from top to bottom, all while being a fully functional children's show about princesses with superpowers.
The only way it could do a "better job" would be by not being about princesses at all, but then the kids who actually need those anti establishment lessons wouldn't watch it. Instead, the queer creators made a show originally designed to sell toys into something more. There will never be another show like it, because despite it being a good show, it probably made less money for it's quality than every other show in the IP
