That video of Alex Hirsch reading S&P notes for Gravity Falls conveys a few things to me:
1) the U.S. entertainment industry (especially animation) is run by older conservative types who make up offensive terms and get really mad about them.
2) the people who run Disney would be the first to fall in line with a fascist regime.
3) most of the media we consume is tailor-made and watered-down to appeal to the tastes of older, deeply religious conservative audiences.
4) conservatism, not the left, is and always has been the biggest voice of censorship in American culture.
