So the KKK was very concerned about Black Lives Mattering?
Sounds backwards.
Seems like John Brown and his attempted insurrection raid is more like BLM and Antifa.
This is the reason that the KKK instituted riots in Tulsa and Miami in the 19 teens and 20s to burn down black owned businesses and almost exactly a century later BLM did the same thing to burn down black owned businesses in Ferguson, Missouri, Minneapolis and elsewhere.
The major differences is that BLM could claim that they didn't specifically target black owned businesses (a lie) because businesses were a lot more integrated a century later.
