MLK got mythologized into some Jesus figure for people to wag their fingers at black people for not kissing people's asses when wronged, had most of his anger at white people, class-based social messages, radical nature, and prison time forgotten, had signature pieces of the landmark legislation inspired by his actions completely gutted a few years ago, and, oh yeah, he was actually murdered.
Because of attitudes like yours, MLK has been fucked over in body and spirit. So don't invoke his name like it's some Yu-Gi-Oh trap card.
