After reading extensively about these characters, the McCarthy period and the HUAC, I came to the conclusion that the HT hated all things Americans. But the HT's rancor and lingering animosity is related to their being exposed as craven, hypocritical cowards. This they could not tolerate.
Joe McCarthy was on the right track but his modus operandi was wrong. His biggest error was to give the HT and their comrades the ammunition with which to fight him. The commie HT creeps used the very same constitutional protections that they sought to annihiliate to defend their sorry rumps.
Yup. The Bolsheviks used our system against us from the very start back when Baldwin created the ACLU and Willi Muzenberg ran the propaganda campaign to portray Sacco and Vanzetti as victims (It was hugely sucessful too. When reading the memoirs of Communist Party members from the 1930s is it striking how one after the next cited Sacco and Vanzetti for the reason they became activists).
