...Instead, Trump is actually fomenting it. Even if it were just stubbornness and not genuine sympathy with neo-Nazis Trump is guaranteeing that they will engage in further marches, in turn guaranteeing further violence. This could be unintentional or not, but regardless, it is now the most urgent grounds for impeachment and removal from office.
Neo-Nazis and the KKK are armed groups devoted to the violent overthrow of the U.S., and they are marching in veneration of a previous institution devoted to the same end. By praising them Trump is now committing much worse acts of treason than his presumed conspiracy with the Russians to commit espionage and hacking against Americans. At best Republicans standing by are committing treasonous capitulation to anti-American terror groups and at the worst are complicit in inciting the violence.
