To the Editor:Kelly L. Ross’ letter of Oct. 1 is yet another stab in the rush by revisionists to legitimize and clean up the shameful period of the blacklist. The very vast majority of the men and women who suffered under the blacklist gave no aid of any kind to any enemy and were guilty only of harboring ideas that were contrary at the time to the establishment. The witch hunt on the whole was invented and used by unscrupulous politicians to further their own narrow ends. It is shameful that people continue to simplify this dark period and demonize the victims of the times. It is particularly shocking in a town where so many people suffered because of this generalized hysteria.
