MLK opposed abortion and thought it was wrong to treat anyone different because of skin color. He was very opposed to segregation, he was a Christian and committed to non-violence. BLM and the democrats utterly oppose everything he stood for. They stand for deliberate pro-black segregation, they celebrate abortion, they are atheist, they use political violence.
Also, he never got wealthy from the movement.
MLK is dead so it does not matter. But suppose he is alive today. Would he be more like Clarence Thomas? Or like John Lewis? Everything changes due to time. So MLK could had “evolved” himself into a race hustler. Or he would be disgusted by the “movement” today?
