I think you can kind of stretch it to be true if you try real hard but it's stupid to blame TikTok for this. TikTok skews younger, and this is a cause that is popular with the younger generation, so yes TikTok will trend as more supportive of this cause and will reinforce those views via algorithm and the algorithm does not necessarily have to care if things are factual or not so popular things will not always be factual. It's a lot of words to not say anything useful, so she's basically one step away from shitposting on Lemmy right now.
Her comments about not knowing the history are interesting to think about though, because I think she's mostly talking about the news coverage some of us grew up with. Remember that we used to think we could trust our news and there's been a lot of coverage on this historically. Most over around 30 have a pretty good memory of the coverage around 9/11 and the 'war on terror' and are pretty much done thinking about the conflict after finding out that the Palestinian government is ruled by Hamas and will at best say "I feel bad for the people who have to live in Palestine". It's even worse when you get to the 40s-50s range and have someone old enough to have watched the news when modern Palestine was kind of forming into it's current form in the 80s. Somewhere in between is anyone who at any point in time heard any coverage at all about the original charter Hamas was founded on, it's rough. Definitely didn't invent it and they weren't the only ones using the tactic, but for a lot of us, Hamas were also the first guys you heard about when you first learned the term 'Suicide Bombing' on the news too. I don't really want to see the numbers, but I do wonder who holds the record for the most suicide bombings they've publicly claimed responsibility for, we definitely at least knew who these guys were. Some people say you have to separate the people from their government and then the government from their past, but that statement resonates less and less depending on how old the person you're talking to is. Just an interesting retrospective. I still think the basis of the comment is kind of stupid, but it does bring to mind some interesting thoughts.
Interesting numbers, other sources out there will say much the same, but I've always felt that pew research bias is pretty minimal: https://www.pewresearch.org/short-reads/2024/04/02/younger-americans-stand-out-in-their-views-of-the-israel-hamas-war/
