The content that bothers part of the American public is as ridiculous as the stuff the American public laughs at Disney for censoring because of China.
For some Americans, the only appropriate protagonist is straight, white and male. There have been some huge exceptions, but that's because there's actually a pretty big market for it and those stories were good enough to blast through those expectations. Does that reinforce the idea that story is the most important thing? Sure, but let's not pretend that the bar isn't MUCH higher for diverse characters. And gay characters? They make up a big chunk of the population and yet are mostly banned in Disney, any characters who lean gay always generate a ton of outrage.
