FULL THROTTLE ANTISEMITISM WITH BLOOD LIBEL

This short video clip of a Black Lives Matter march in Washington DC is the part which includes the above chant.

Prior to this the chanting included simply "black lives matter" before progressing to the usual anti-Israel chant "from the river to the sea, Palestine will be free" which is about wiping Israel off the map.

But then it goes into the old style antisemitic blood libel about Jews/Israel murdering children.

Other BLM rally chants include:
"We don't want no two-states, we want 48" (meaning 1948 before modern Israel)
"There is only one solution, intifada revolution" (a call for mass murder and terrorism)

AJA calls out BLM is racist, antisemitic to its foundations.
