Why protesters were targeting Biden

Biden faced sustained criticism from progressive Democrats, human rights advocates and pro-Palestinian activists over his administration's support for Israel during the Israel-Hamas war.Critics repeatedly called him "Genocide Joe" over continued US military assistance to Israel. They argued that the weapons and defence funding enabled Israeli forces to kill and displace civilians in the Gaza Strip.However, military experts have also noted that Israel took unprecedented measures to minimise civilian casualties while targeting Hamas militants operating in densely populated urban areas.
