"I Ain't Reading All That; Free Palestine"
The meme enrages Israel supporters because Israel apologia depends on mountains of verbiage to spin obvious atrocities as reasonable and appropriate. At some point the kids noticed this was happening, and started dismissing all the narratives.
...Without mountains of narrative, all you’ve got is a nonstop deluge of raw video footage depicting the blatant genocidal criminality of Israel. No narrative overlay is required atop a video of a baby beheaded by Israeli military explosives. It stands on its own. You’d only need narrative to explain why the footage of the headless baby doesn’t say bad things about the side that’s dropping the bombs.
..Manipulators understand that they can use narrative to promote material agendas if they can get people to believe those narratives, and it enrages them when people handwave away the narrative and stick solely with the raw data of material reality. If you’ve based your life around trading empty narrative fluff for real material resources and gains, having your narratives dismissed can feel like holding a huge pile of currency that suddenly got devalued to zero. Of course the manipulators would be upset about this.
With your last paragraph in particular, no that wasn't clear but I'm glad to hear it. I don't think this meme is about the quarter of people genuinely asking questions. Instead, I think it's about the Zionists who spread multiple points of misinformation. And when someone responds with sources to debunk those claims, they simply ignore, deflect, and spread other points of misinformation.
I can't blame people for wanting to tune those people out, they are exhausting. I still think it's helpful to reply with sources so the people reading have a better idea
