In the Spanish Civil War, Franco's Nationalist/Fascist faction (https://en.wikipedia.org/wiki/Nationalist_faction_(Spanish_Civil_War) ) won with the backing of Germany and Italy. The Republicans/Communists https://en.wikipedia.org/wiki/Republican_faction_(Spanish_Civil_War) lost, in spite of the Soviet Union pouring in men and munitions. Stalin used the opportunity of the war to kill off the non-Stalinist Communists who joined up to fight in Spain.Yeah! When I see that it makes me think guns are 'ok' now as long as your not dangerously teaching.
Speaking of commies, I recall a bit about the Spanish Revolution or the one with Franco and all the famous writers that went over to fight before WWII. I think even the Nazi's were helping with the Stukas dive bombing. So the different commie groups fought together to over throw the gov't and after they won they went around and killed off or imprisoned the lesser communist faction after they help them win power. I gotta think there were a few folks deemed 'prohibited professors' over there back then.
