The Instagram page’s transformation from a platform supporting Hill workers across parties, with fans even on the center-right, into a mostly single-issue anti-Israel advocacy page is reflective of broader trends in many progressive organizing spaces since October — leaning into anti-Israel stances or facing internal and external dissent over their refusal to do so.
