communist supporters in Hollywood [which was probably true, but didn't need the McCarthy response].
You're confusing the rambling, over-broad 'House Un-American Activities Committee' (HUAC) of the 1950s with Senator Joseph McCarthy's targeting of foreign agents in the State Department in the 1960s.
McCarthy went after literal communist infiltrators in positions of power, from a different legislative body, in a different decade than the Hollywood folks. The two have been conflated because there were communists in the State Department, and the communists in the media don't like people knowing about it.
