Why do American History books print so much miss information about the origins of the civil rights movement?

The civil rights movement started right after WWII when 1 million black soldiers where discharged from the military and they had to go back to civilian life. First rate soldiers where treated like second cl citizens, and they refused to let that be their reality. All these men went back home and decided if a man can't go into a bar and drink a cold beer amongst other men, then the "STATUS QUE" had to be "CHANGED". This started out breaks of resistance all over America from these men. The one thing that service brought them was how to organize and plan. With these new tools, they would inspire other black people like Martin Luther King, Malcolm X to take up their cause. The American media blocked a lot of turmoil in the country and refused to shine light on it. The Germans reported this news all across the world (the miss treatment of black people), and America was the laughing stock of the whole world, thats when thing began to change for black people, not because white people where nice enough to give us equality.
