I'm half way through and kinda iffy on this one. Like I think she was really dismissive of the fact there are a lot of direct material reasons for this kind of hatred. For example with the Marie Antoinette thing, saying she did nothing wrong just ignores all the horror that supported her. The fake quote about cake was only effective in the first place because it spoke to a truth about the structure of french society. They both knew that as bad or worse was being said all the time and there was utility in using the right rhetoric to end those conditions. It's like the video pays lip service to Marx at the start as a joke, but there is real truth to the idea that a lot of this aggression is manifested class conflict even if it does look like stupid tweets.
I feel like she falls into the misconception you have to be a marxist, attempting socialism or have some other signifier at which point you can be taken seriously as a political actor, which leads to minimizing the larger forces at play with pop psychology.
Feel free to go look at twitter screenshots for 2 hours instead.
