I do not support the BLM protests as they had them because they were violent, yet I support black rights. I understand also Martin Luther King Jrs statement not to have violent protests because it makes the protesters out to be the bad guys.
I was at the Dakota Access Pipeline (DAPL) protests in standing rock protesting against the encroachment of native Americans rights. As and I told them also, "it is not good if you break the law, it makes it look like you are the bad guys. Rather stress how much THEY are breaking the law.
I do not support violent protests for the most part, unless life is at stake.
