Even the average alt-right rage tuber is smart enough to stick to softer targets like The Marvels and not criticize Black Panther in their gazillion anti-woke rant videos (at least not in thumbnails). The fact that Peltz went after BP too doesn't just show his bigotry but also reveals he is way out of touch if he doesn't realize how big those movies were financially and that they were the biggest splash made by Disney blockbusters in a long time.
Even if I were purely cynical and just into the numbers and PR, that would be a red flag for me right away.
