The question from DMarks:
True, some mascots have been eliminated, but that's probably because liberal educators are in control of schools. I'm not sure there's been any movement against mascots among the masses. If we polled people on whether Chief Wahoo is offensive, for instance, the numbers might be the same as in 1990.
Look at some of things that have appeared recently: Apocalypto. Pathfinder. Comanche Moon. COWBOYS & INDIANS vol. 1. RIPCLAW PILOT SEASON. THE FOURTH HORSEMAN #1. OutKast's Grammy performance. The Zagar and Steve commercials. The Swedish documentary. Etc.
I could go on and on. These are literally, not figuratively, as bad as anything that appeared in the 1950s. Judging by these examples, we've made no progress since then.
Why is that? Since the conservative moment became ascendant in the 1980s, there's been a backlash against liberalism and multiculturalism. It's become somewhat acceptable to be racist. Witness Mel Gibson, Michael Richards, Don Imus, George ("macaca") Allen, the reaction to 9/11, the reaction to Katrina, the Jena Six, etc. Sure, people are criticized when they make racist remarks. But they also feel free to make such remarks, and they get more support than they used to.
