i think he means that the oppressed black people should start fighting rather than protesting. in a way, singing could resemble a peaceful protest, but swinging is a kind of punch (in a way). this is just my guess and i could be wrong, but this is as clear as it gets to me. Malcom x was the type of man to always fight for his and their black freedom with aggression to put him in front of the peaceful MLK protesting's. because they would never work how they work nowadays. Thank you.
