I have been pointing that out for decades. That almost everything known of that era is a complete lie.
Want to see a Braindead nutcase lose their mind? Ask them how many people in Hollywood that Senator McCarthy put on the blacklist.
Then when they give you their number, calmly explain to them as if they are children that was actually the Democratic Party in the House, and it was the House Unamerican Activities Commission. Specifically, it was Congressman Edward J. Hart (D) of New Jersey that led it. Being a Senator and not a Congressman, Joe McCarthy had not a damned thing to do with that. And his only interest was in government employees, and nobody else. It was the Democratic led House that went after every day people.
Then ask them to explain how one of the most powerful and influential members of his team was Senator John F. Kennedy (D) from Massachusetts, and the attorney that oversaw the investigations was Robert Kennedy. And neither John nor Robert Kennedy ever attacked, denounced, nor spoke badly of Senator McCarthy or the investigations.
