This is no time for people of conscience and good will to sit by silently. To be silent is to give tacit approval of the hate march and all the sickness it stands for. As of this writing, the hate groups have driven three cars into the crowds of counter protesters, creating multiple injuries.
Update: 8/15/17: After the appalling press conference Donald Trump held in Trump Tower, where he attempted to normalize race hatred, white supremacists, and compare and contrast them with those who came to demonstrate against hatred and try to make both sides the same, which they will never be, protest loudly and bluntly this immoral response to a tragedy that left three dead and 19 hospitalized. Protest as well Mr. Trump's assertion that honest reporters are fake news, as that is what authoritarians do. Do not be silent at this time, or you are complicit with those who hate and excuse hatred. Never before in my life has I seen a president do what was done today, which led to congratulations from active, prominent members of white supremacist groups.
