Martin Luther King was considred a moderat Black Civil Rights activist, Malcolm X by contrast was considered an extremist. Malcolm X was reported to have said that if it was not for people like himself Martin Luther King would not have been able to get his message accepted as moderate. In other words Malcolm X acted as a foil for the presentation of the actual message. Hamza Yusuf if he adopted a 'extremist' position would become isolated and labeled an extremist, he needs to tailor his message to fit into his society without being isolated...I think he is doing a good job, May Allah Bless him and give his success in everything.
