The article says "The group had gathered to protest plans to remove a statue of Confederate Gen. Robert E. Lee, and others arrived to protest the racism".

A judge had put removal of the statue on hold and people were there to rally in support keeping the statue of Lee.

I think people have a right to gather, demonstrate and protest peacefully in the U.S.A.

The demonstrators were peaceful to start. Who started the violence?

If anti-rally protesters hadn't showed up, would violence have erupted?
