For those of you that criticize their methods not message. Let me just say this, during the many civil rights struggles (lgbt, black, women) people of these minorities had to "be rude" and be less than thoughtful with who they targeted for protests. But it's not about being nice and waiting on progress. People are dying while we criticize someone's tone and timing. Once I realized the historical backdrop, the context for the BLM folks...I can't fault them. By the same high standards we hold MLK and others to, we have to hold them to that standard as well.
An honest question: whose campaign events or public speeches were disrupted by MLK? I am certainly not a student of the era, but most of the notable civil disobedience I can recall were boycotts, sit-ins, and marches that were designated, independent events. They weren't attempts to disrupt, co-opt, or upstage someone else at their own separate speech or rally.
