I have to call you on this one. Name names. Who? How many? Where?
Svend Robinson, a New Democrat MP (think the American Democrats basically in line with The Rev Jessie) is a son of Americans and a habitual anti-U.S. rabble rouser. You may have seen him in Palestine a few months ago trying to scold an Israeli soldier. Lucky for him he didn't get his head shot off.
I'm tempted to include Maude Barlow here but honestly I'm not sure, but in any case she's a complete nutbar regardless.
There's more that I just can't think of right now, but they manage to crop up from time to time and it's really annoying.
