Madness string 86743

My dad actually did end up on an FBI list in the 60s when he was a student. He listened to shortwave radio, and he found a Chinese station and mailed them a reception report, which is basically a 'Hi, I live here and listened to your station on this date'. After this, the Chinese government started mailing him Communist materials, including an English translation of Chairman Mao's little red book. Dad wasn't a Communist and gave all the stuff to his friends at the university who were. After a few months of regular mailings from China, the FBI sent Dad a letter saying 'We know you are receiving this material in the mail. Do you wish to continue receiving it?' Dad wrote back saying 'yes', because he figured it's a free country and it's his free speech right to receive Commie propaganda if he wants to. So he wound up on a list as a Communist sympathizer.
