None of his targets had anything to do with Hollywood. That's as silly as the prevailing disinformation that "Senator" McCarthy headed the "House" Committee on Unamerican Activities. McCarthy was after Communists in the Administration and State Department.
The so-called Hollywood "Black List" was the result of hearings before the aforementioned House committee and was instituted by the studio heads themselves. The embedded Communists Joe was after have muddied the waters to the point that even McCarthy defenders have bought into their lies.
And pea-brains like Meryl Streep are STILL going after Disney.
The Hollywood "blacklist" was by anti-commie studio heads, like you said.
Joe McCarthy had absolutely NO power over Hollywood in the 50s
Even then the notion that a republican could tell leftist Hollywood anything is laughable.
Don't forget that Ronald Reagan was a liberal democrat at the time, and once he got a good look at the Reds up close, he switched parties.
The pinkos threatened him, physically.
It makes me wonder just WHY today's stars are roughly 98% hard left.
My theory is that there is either some real "dirt" on them, or they've been threatened otherwise.
Probably some big names were "gay for play" and there is photographic evidence that makes them toe the line, lest they become unbankable.
