CHARLESTON, S.C. — Former Vice President Joe Biden on Saturday evening urged Americans to stand up to hate groups – and took direct aim at President Donald Trump, who he said “has publicly proclaimed the moral equivalency of Neo-Nazis, Klansmen, and those who oppose their hate.”Speaking at the centennial fundraising dinner for the Charleston branch of the NAACP, Biden said, “This is a moment for this nation to declare what this president can’t with any clarity, consistency, or vision: there is no place in America for hate groups.”The speech at the Gaillard Center — across the street from the Mother Emanuel AME church where nine African-American churchgoers were murdered in 2015 by a white supremacist hoping to incite a race war — was one of Biden’s first since the fatal violence last month at a neo-Nazi march in Charlottesville, Virginia.
