why does Martin Luther King Jr. deserve to have a holiday named after him

i personally think that martin Luther King Jr. should have a holiday named after him because he stopped segregation and fought for blacks to have a freedom of speech.Dr. king wanted all people to be created equall and all descrimnatation to stop.King also thought that black and whites jews and gentiles should united as one.So Dr, King deserves the holiday to be named after him because he made big changes in the world..
