It's not racism though, it's retribution for 150 YEARS of slavery and oppresion
Racism is a poison. It pits groups against each other, causes confusion and innocent lives to suffer. And, as a result, there are opposite reactions. When one group is tribal against another, it doesn't take long for the oppressed to become the oppressors.
Claiming all white people are national socialists doesn't help anyone. Likewise, saying all BLM supporters are terrorists is just as bad. In order to end racism, people need to put their differences aside, stop blaming majorities for minorities, and understand that love is the cure to hate. Even in the face of oppression, it is key to hold your ground and avoid retaliating, as retaliation breeds worse consequences.
When a racially motivated crime occurs, the best course of action is to understand why it happened and bring people together so that it doesn't occur again. Pointing fingers and pushing people under the bus just causes history to repeat itself.
