Hmmm...time is what your argument lacks. The SA didn't build gas chambers in Poland, but they were the starting point for later evils. BLM is becoming more militant and accusing one specific group for all their problems. What separates a BLM rioter who wants to shoot a cop and burn restaurants that serve cops from a Brown Shirt who wanted to shoot a Jew for walking on the sidewalk and burning cafes that served Jews? It only took Hitler less than 10 years to turn angry mobs into a genocidal army. Just give it time.
