Trotted out by ignorant woke dummies. In his 1967 Stanford speech MLK also says: "Let me say as I've always said and I will always continue to say, that riots are socially destructive and self-defeating. I'm still convinced that nonviolence is the most potent weapon available to oppressed people in their struggle for freedom and justice."
Using MLK to defend or advocate violence is astonishingly ahistoric.
For example:
"X is a bad person, therefore their argument is invalid" is an ad-hominem. Bad people can still make valid arguments.
"X's argument is both invalid and in bad faith, therefore they are a bad person" is a logical inference.
It is the difference between "If you believe X then your school must have had brain-dead teachers" and "If you believe X you are brain-dead"
"They asked if our own nation wasn’t using massive doses of violence to solve its problems, to bring about the changes it wanted. Their questions hit home, and I knew that I could never again raise my voice against the violence of the oppressed in the ghettos without having first spoken clearly to the greatest purveyor of violence in the world today: my own government."
