Wayne requested 3-A deferment and then his studio got him a long term one. And when people gave him guff about it after the war he went full on zealot for McCarthyism and hardcore supported HUAC the group that got hundreds of his fellow film makers blackballed, sometimes on flimsy evidence, ruining their careers and lives to make himself look patriotic.
And some of them had NOTHING to do with Communism.
I like Wayne's movies, but he PLAYED soldier in movies and got deferment while many of his fellow stars did their duty. And he doesn't get a pass on that just because he blustered about patriotism later and made some war films. He screwed people over in the name of "Patriotism" while being a draft dodger.
