What I can not forgive in modern Academia is the purposeful distortions and lies they tell for propaganda purposes.
Every time somebody brings up Senator McCarthy and goes immediately into the activities of HUAC and the blacklisting of actors and others in Hollywood, I just want to smash their head into a wall. The Senator was involved in the Army-McCarthy Hearing in 1954, and was only interested in individuals who had security clearances and actually worked for the US Government. People in the military, people working in the State Department, people like that.
The House Un-American Activities Committee is the organization that went after people who did not work for the Government, like actors. And that was actually started by Congressman Ed Hart (D) in 1945. That is the organization that conducted the "Hollywood Blacklist", and that started in 1947 - 7 years before the Army-McCartney Hearings. And continued for almost two decades after the McCartney Hearing (finally ending in 1975).
What bothers me not so much that it is "propaganda", but it is an almost absolute lie. Yet a lot of people want to believe it and will absolutely ignore facts because they contradict their beliefs.
