I have a Flag Smashers shirt... go figure, they speak to me.
I was putting it on a couple days ago and I paused and thought about it, and suddenly realized the immensity of the propaganda - the great Captain America destroying the evil socialists who think resources should be shared by everyone, and that nationalism is a barrier to truly having 'one human family'.
Blew my mind it took me this long. Also made me wonder if they were dug up from long ago comics when America was openly and blatantly monitoring and persecuting socialists and communists (specifically picturing the scenarios and time illustrated in Oppenheimer). Haven't had a chance to dig in to that part yet, but I will right now!
