All art has to be viewed in the context of the prevailing culture of the time, you can't retroactively censor stuff.. the same stuff made today that we all think is "right on" and progressive will be viewed in 30 years time as antiquated and problematic. (apologies for using that stupid word in two consecutive posts)
As if terms like "people of colour" is going to age well... if you told people 15 years ago that the question "what is a woman?" would be almost impossible for politicians to answer and seen as toxic, they'd have thought you were insane.
