It's worth noting that not too long after this speech, Malcolm X embarked on the Hajj, afterwards recanting his prior black nationalist stances when he realized that all races are subservient to God.
He then left the Nation of Islam and later joined mainstream Sunni Islam. After he left the Nation, Malcom X's views evolved. He extended olive branches to MLK and other organizations like his to try and create a united front to advance the cause of Civil Rights in America.
Malcom was evolving into a liberal.
