First #RedTriangles at #ProPalestineProtests were the #RedTriangle lapel pins of Spanish #Communists and other #leftists in #Madrid on #9October2023
#Qassam didn't use them till after the ground invasion of #Gaza on #27October2023
They're very subtle unless you look carefully, so possibly a coincidence, but it's a close coincidence that it's used by the Europeans who were out on the streets already by 9 October 2023?
They're also on the flyers.
