Across the United States, college campuses that were once alive with anti-Israel protests have fallen noticeably silent as Hamas turns its weapons against fellow Palestinians in Gaza, raising uncomfortable questions about the true allegiances behind the movement.

Late-night host Bill Maher highlighted the issue during Friday’s episode of Real Time with Bill Maher, asking his guest, billionaire businessman Mark Cuban, where the so-called “keffiyeh-wearing college kids” have gone now that Hamas is “shooting everybody.”

“Where are the protesters?” Maher pressed Cuban. “Suddenly, the keffiyeh-wearing college kids are very quiet,” he noted, echoing the frustration of many who watched the nationwide demonstrations in prior months. Cuban agreed, responding simply, “Shooting everybody,” which Maher repeated.
