Oh for pete's sake, the Trump/Bannon party don't want "racial harmony".
They don't want diversity at all. That's what Bannon has been saying all along.
They don't want to be compelled to share schools, neighbourhoods, cities, states and the country or breathe the same air as people who do not belong to their self defined "white" race.

The alt right people were carrying signs saying they were Nazis and KKK.  They were chanting anti semitic slogans.
How many more ways do they have to say it? 
They don't like anyone who isn't like them and they will make life difficult for Americans who don't agree with them.  
They went on their websites to praise and thank the President for not condemning them.  They are very pleased with themselves.
