The poem memorializes the workers' uprising against the czars. Some, mostly secular, Jews supported the communist revolution seeing it as ushering in a new world of brotherhood and justice and participated in the uprising. The poem in no way shows any Jewish tradition of hurling stones. Stones and barricades have been used against soldiers and police officers in peasant and worker uprisings in Europe - not against innocent civilians, and there is no "Jewish tradition" of attacking people with stones.
