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.
