See, I think you do. I think you understand that BLM is a pretty big movement, 99% of which is nonviolent. I think you understand that the movement would have been better off if called itself Black Lives Matter Too, which is what it always proclaimed. Not that white lives don't, which is how it's critics (willfully) misinterpreted.
It's a civil rights movement. Unlike the Klan, which is an anti-civil rights movement.
That's why there can be no moral equivalence.
It is the exact same argument made by segregationists in the 50s. And earlier - Huey Long always said the civil rights movement and the klan were equally violent and bad....as if the ends didn't matter.
That is Trump's moral failure here. And yours.
