Political correctness and language codes are not new. I think what was new is the idea that people could rally around the banner of awareness, and thereby avoid disputes about solutions. This is why many of these topics lose momentum once their followers get the attention and have to deal with the hard and less popular questions of how to fix something.
I think what most people call "woke" is probably just a reaction to the obvious emptiness of many of the things politicians like Kamala Harris chose to focus on whilst ignoring more concrete issues. A lot of it was stuff there never was a solution for.
