Liberals weren't demanding anything. They were saying, "vote blue no matter who" and, "how dare you criticize Biden, you Trump supporter!" while giving bad faith knee-jerk responses to all pro-Palestinian positions, particularly (1) pivoting to alleged increased antisemitism for which there is virtually no evidence on the left (purely an attempt at deflection) and (2) trying to extract condemnations of Hamas and reframe the narrative as Hamas vs. "Israel" having "a right to defend itself" (mass murder children).
Liberals were doing the exact opposite of demanding anything remotely pro-Palestine. They were defending Israel and criticizing (and oppressing!) pro-Palestinian voices and loudly announcing that they would fight against any electoral consequences for those enabling the genocide.
