Maybe where you lived. Not where I was.
My dad, a Scottish immigrant who grew up in So Cal where businesses and entities that discriminated against blacks were like as not (rightly!) boycotted and criticized, was ONE PISSED OFF DUDE in the U.S. Navy during WWII, when policy was to make stewards out of all black sailors, regardless of their qualifications. Dad was FURIOUS that a black guy on his ship, who had a degree in engineering, for crying out loud, was PREVENTED from being the officer he should have been, and whose skills and leadership could have saved American lives in battle.
My dad always maintained that a LOT of American veterans saw this horrifically stupid, mindless discrimination in WWII, saw how it actually endangered their lives and ability to win the war, and that it was a MAJOR force in the anti-segregation movement supported by REPUBLICANS and opposed by Democrats that followed during the decades after the war.

Korea and Viet Nam had significant effects, as well.
