I find that it's always interesting to THEN consider, okay -- while there's no centralized board or anything -- what does e.g. American censorship go after?
Anything you can think of you will be able to find that content. We simply don't have the kind of censorship that China has. Comparing the two is ridiculous.
You're missing the point. American censorship doesn't have to be comparable for the question of what can be learned about our cultural bias from what we censor or self-censor to be interesting. What do we eliminate or simply refuse to produce because we can't bear to have our children see the world that way?
