It was such a disgrace that he was denied reentry to this country. The famous person who introduced the Beatles to this country,Ed Sullivan, was one of the right wing McCarthyism villains.
Now the universities have left-wing McCarthyism. Right wing McCarthyism eventually ended. I am not sure when the left-wing McCarthyism will fade.  For example, Harvard University has a $50 billion endowment, which makes it almost immune to criticism and very slow to respond. Although, Harvard and other major university, anti-Semitism could be criticized with the same remarks that were used to end the right wing McCarthyism. Harvard University do you have any sense of decency or shame?
