WARREN — Disgusted by the recent appearance of white supremacist stickers on signs along a main thoroughfare here, several dozen demonstrators rallied on Sunday in front of Town Hall, where speaker after speaker called for individual and political action to curb racism. “Now is not the time for complacency, fear or denial,” said Mel Bynum, one of the organizers of the Warren Spread Peace Protest Rally. “Hate in this country is as epidemic as COVID-19. There is no cure for racism — no vaccine — because such hatred, though born of ignorance, is taught. No one is born racist. Seek truth in facts, not stereotypes or agenda-inspired lies.”
