I would argue it's always been such, but maybe the difference is that our ideology used to be projected through megaphones and now it's just through dogwhistles, and the latter leads to disingenuousness, suspicion, needlessly parsing language for hidden meanings and so on.

I know a bunch of people that all liked the eye-rolling Netflix revisionist diversity fantasy Hollywood, but for me to critique it I have to first counter any assumptions that I am opposed to diversity itself, when what I am actually responding to is the way that revisionist diversity fantasies re-entrench a whitewashed past by leading us to believe that the only way to locate diversity in the past is by inventing it in the most condescending ways possible.
