No the point is that Americans will think you're moralizing even when you don't intend to moralize. It's like portraying a character kicking a puppy, when the author comes from a culture where kicking puppies is just normal everyday behavior.

Americans can handle complicated stories with ambiguity and no clear good v evil.

But there are loud camps of culture warriors who raise a fuss if it's not "safe for kids" and a whole industry of grifters who amplify this, because getting people angry improves their TV ratings and the political campaign funds.

There are a lot of managers in the arts and culture industry (editors, producers, museum directors etc) who are rarely rewarded but often punished for resisting the culture warriors.
