Question: hollywood remained the one voice of protest during the red scare

Answer: No, The Hollywood blacklist - as the broader entertainment industry blacklist is generally known - was the practice of denying employment to screenwriters, actors, directors, musicians, and other American entertainment professionals during the mid-20th century because they were accused of having Communist ties or sympathies. Artists were barred from work on the basis of their alleged membership in or sympathy with the Communist Party USA, or their refusal to assist investigations into the party's activities. Even during the period of its strictest enforcement, from the late 1940s through to the late 1950s, the blacklist was rarely made explicit or verifiable, but it directly damaged the careers of scores of individuals working in the film industry.
