Does the author seriously think he has made a compelling case here? "Anything that infringes upon our art can be considered a direct threat to our culture" is a statement of belief, not an argument nor an explanation of the reason for that belief. Art and culture are inseparable in ANY culture, that is tautological. The rest does not follow and the author has not demonstrated that it does.

And Tonto and Pocahontas are supposed to be examples of writers wanting to explore the lives of people who aren’t like them? Since when is that the intent of a children's fairytale Disney cartoon and a children's adventure TV show? Snow White also had perfect hair and makeup and talked to birds and forest animals, nobody though that was a serious attempt to explore the life of a princess in the Middle Ages, anymore than Bonanza, Lassie, Leave it to Beaver, or any other children's shows of the 50s or 60s were attempts to explore those realities.
