Maybe I haven't been paying attention. I hear a lot of talk about Trump and supporters being white supremacists, but when I ask his accusers, they aren't able to articulate very significant evidence at all. Most such conversations end with implications that I'm a racist for lacking the astute progressive hearing required to perceive Trump's dog whistles. The irony that dog whistles are (by definition) intended to be perceptible only to actual racists is apparently lost on many progressives.
