The media aganda is to equate anything conservative, and escpecially nationalist with “white supremacists”. White’s who are nationalist are “white nationalists”, therefore attacking them is just like fighting the Nazis in WWII. Trump gets it and is the only one standing up to them.
Remember: the “Nazi Party” translates to the “National SOCIALIST Party”; last I heard, the socialists were left-wing (ie LIBERALS).
Any expressed opposition to them is considered by them to be Nazi, white supremacists, racists, etc.
