Earlier quoted context omitted.
This is a distraction and diversion from the original comment. Hollywood is not at the scale of the internet. Some privileged people got cancelled in Hollywood, who cares. When a hard working person gets cancelled by saying something stupid, the consequences are back breaking.
Forget Hollywood. Imagine trying to build the career of your choice as a black person, or a woman or an out gay person in that same era. Society was casually blacklisting the literal majority of Americans from most professional realms.
Whereas today it's a new phenomenon, that gets progressively worse even though the problems you've mentioned (regarding blacks, women, gays, etc) are at their historical lower point.
So while America was progressing then, this is a regression now.
And it also affects blacks, women, gays, lesbians, republicans, demoracts, old-style lefties, and so on -- all of those categories have had members cancelled or mob-attacked for wrong opinions... (even someone like Dave Chappelle, who is a comedian of all things, has been attacked on such grounds).
