Good point! I still find it confusing that these hate groups are always associated with the right-wing. Certainly the left-wing has more of a racist history.
Dickstein, it was discovered when the KGB files were opened after 1991, was a Soviet agent. The NKVD was paying him $1,250 a month at the height of the Great Depression--about $15,000 a month in 2001 dollars. On the side, he sold the Soviets visas for their agents (Dickstein chaired an immigration committee).
