I think this is a twisting of the faith of MLK jr.
Your argument deals with a paper King wrote in 1949...which he seems to repudiate in his 1954 sermon, “Rediscovering Lost Values”.
King was not always a born again Christian. He became a preacher as a vocation. But, his experiences with death threats, and bombed churches which killed little girls; being beaten and imprisoned, having dogs set on him; straightened out his thinking, and set his eyes on Jesus! He speakes about the long night he spent as he realised that he couldn’t depend on anyone, but Jesus to save him!
Here is another quote from a letter he wrote from Prison, that his followers should heed:
“I must make two honest confessions to you, my Christian and Jewish brothers. First, I must confess that over the past few years I have been gravely disappointed with the white moderate. I have almost reached the regrettable conclusion that the Negro’s great stumbling block in his stride toward freedom is not the White Citizen’s Counciler or the Ku Klux Klanner, but the white moderate, who is more devoted to “order” than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: “I agree with you in the goal you seek, but I cannot agree with your methods of direct action”; who paternalistically believes he can set the timetable for another man’s freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a “more convenient season.” Shallow understanding from people of good will is more frustrating than absolute misunderstanding from people of ill will. Lukewarm acceptance is much more bewildering than outright rejection.”
There’s room in there for the argument of quite a few fine points....
