He said the white man is the devil and if a plane full of white people crashed it was Gods will to kill the devil.Malcolm X never stated that he wanted "ALL white people dead".
Prior to his "change of heart", he advocated for seperation, not a race war.
He was also an advocate for black citizens DEFENDING themselves by any means necessary if attacked, instead of being passive, like MLK.
Malcolm rejects non-violence in the case of self-defense.
