IME a lot of millenials and younger that are "progressive" are too left for what can be considered "acceptable content" on corporate platforms. Tiktok has pretty good content in this area, but I think a lot of it boils down to the biases of liberal broadcast media owners not keeping up with the kind of content people want to hear. Anything further left than liberalism is considered a "national security issue" so you don't get any interesting viewpoints. Even breadtube is pretty milk toast. I'll just stick to my hip hop and punk jams tyvm.
