There is a sizable industry still doing that exact same thing today. Instead of saying that they’re “politically incorrect” they say that they’ve been “cancelled”. It seems like this line of discussion is not only alive and well, it is quite lucrative too, which more than a tiny bit undermines the core premise of what being “cancelled” means.
> R rated movies were far more successful at the box office, with lots of questionable content by today’s standards.
As a sibling comment pointed out, this is factually incorrect. You also need to adjust for the fact that the internet exists, and various social and economic pressures are sending more R rated content directly to streaming.
Are there fewer R rated movies in theaters because of how sensitive we are, or are you just preferring to watch R rated content at home rather than in the theater?

Given the rise of the alt right and the dirtbag left, pushing boundaries is still very popular and lucrative.
> Today, the academic and cultural power brokers are the biggest champions of shutting down “objectionable” speech.
