Max Blumenthal is experiencing what goes around coming around.
Having blamed various critics of radical Islam as well as international Zionism for the 2011 mass murder in Norway, unfairly, Blumenthal now is in focus because the Overland Park shooter was a big fan of Blumenthal’s Jewish money and Israel Lobby conspiracy theories.  The shooter was a Neo-Nazi and KKK leader for whom Jewish control of the media and international money was a core belief motivating hatred of Jews.  That’s a shared space for anti-Zionists of multiple political ideologies and religions.
Specifically, the shooter focused on Blumenthal’s theory that Jewish campaign donors were trying to buy the 2012 U.S. presidential election for Bibi Netanyahu, as expressed by Blumenthal in a lengthy article and a Russia Today television interview, to which the shooter linked.  It’s ugly stuff, but the type of ugly stuff for which Blumenthal has become known.
