Trumbo wrote some of the greatest Hollywood movies - including one of my favorites, Lonely Are the Brave. Very talented and yet given to destroying the freedoms of a country that so blatantly rewarded him. Weird, weird, weird.
The history of no country on earth is perfect. Bad things have done by every different group of people since the dawn of history. But embellishing the bad does not disqualify the good that has been done in general. That's what leftists miss. But the Hollywood commies thought their wonderful Stalinist Soviet Union was the dream country. How deluded/crazy can you be to believe that?
