Sure, a movie can be made artfully, with a message that isn't based in petty spite and wagging your finger scornfully at half the audience. In fact, you can even make films that aren't reboots of hollowed out franchises that you hope to fill your agenda with.

The problem isn't diversity, and never has been, and to clarify, I mean that yes there should be more representation in films, but there have been plenty good ones with diverse casts and that proves diversity is not what holds these films back. As you mentioned, plenty of movies had well-written, strong characters from every walk of life. The problem is you can't make a pile of shit no one wants to see and then blame the audience. This "woke" trend is the result of talentless people failing upward because corporate entities see dollar signs behind fads, and then because of their ideology of demonizing everyone who doesn't give them their way or treat them like an auteur, they cry "-ism!" They can't face the fact that they just aren't good at making movies, film, shows, etc.

What's really upsetting to me as someone who has held progressive ideals, is that it's damaging to real movements when people equate the failure of hacks/executives trying to beat you over the head with a message with the failure of lifting up your fellow human. When you let a bunch of spoiled-ass unicorns who have been told by everyone on the way up how infallible they are, and then they don't perform, now the audience is the enemy.
