No disrespect intended but McCarthy had no “Hollywood blacklist”. Please don’t perpetuate this lie.
Those who spread fake news have been effective in disseminating fake history. Just google using search terms such as "McCarthy AND 'Hollywood blacklist" or "McCarthy AND 'Hollywood Ten" and the number of hits you receive will be in five or six figures.
Thanks to generations of liberal pundits, professors and pedagogues, the myth of McCarthy's association with the "Hollywood blacklist" has been entrenched despite the fact that McCarthy's Senate Committee on Government Operations had no interest in or authority to probe Hollywood.
