When McCarthy did that to Hollywood and big media, it was an outrage, now crickets
McCarthy didn’t do that to Hollywood.
He didn’t appear on the scene until February 1950. You are thinking of the House Un-American Activities Committee (HUAC) which was a committee in the House, not the Senate which McCarthy belonged to.
For what it is worth, McCarthy was spot on about his specific issue, which started out as communists in the State Department, and ended with Communists in the Defense establishments.
He has been shown by archives to be right on nearly every person he targeted.
