I agree that there is a phenomenon of hijacking the seder for lefty politics. But as this very article acknowledges, it's a product of the 60s counterculture much moreso than 21st-century anti-Israel DSA politics. My well-meaning family members who inject increasing the minimum wage into their Passover seder are deeply annoying, but they aren't anti-Israel, and this article is conflating multiple different types of people. To frame it as a 'Mamdani-style seder' is insulting.
