This is something that unites almost everyone from Nazis to Lefties and Islamists.
The Protocols of the Elders of Zion. A shady cabal of Jews running the world. The mighty Israel Lobby.
Once you buy into this conspiracy theory you not only become a nasty little racist tarnishing an entire race with an evil James Bondesque ulterior motive of world domination, you also become obsessed. You start seeing Jews everywhere.
Paul Wolfowitz is the head of the world bank. Michael Grade is Director General of the BBC, Coca Cola is Jewish, Starbucks is Jewish Jews, Jews, Jews everywhere scheming and murdering. It gets so bad that it's not enough to just hunt for Jews in high positions you have to accuse gentiles in power of being undercover Jews. Rupert Murdoch is a Jew, Tony Blair is a Jew wasn't George Bush's great great grandfather a Rothschild. Wait a minitue is Bilderburg a Jewish name..... Oh my god!!!!!!!!!!
I'm nearly convincing myself

Seriously anyone who goes in for this stuff whether it is Stop The War activist or a Muslim peace protester is a nasty racist in my book.
