I have a deep and searing memory of being surrounded by a group of LaRouche volunteers in 1990 at the entrance to the LA County Fair in Pomona. At present, his volunteers focus almost exclusively on an anti-Cheney hook to grab the attention of passers-by --and, hey, who wouldn't want to be on an anti-Cheney crusade? Many of the volunteers I've seen around Los Angeles staffing LaRouche tables are far too young to remember his regular tirades against gays and lesbians (at the time, we were his new-found cause-- even as he was being led off to jail for fraud) much less his unsuccessful attempt to round up people with HIV and put them in concentration camps. That is no exaggeration.
Oh yeah, and he said that British royal family put Hitler in power. It's a little known fact that a great deal of the British royal family's wealth is derived from almost half a millennium of involvement in the slave trade; but there's evil and then there's evil. And as evil and complicit as the monarchies of Western Europe have been in the genocide of peoples the globe over, I doubt they can claim Hitler as their doing. Not on purpose, at any rate.
