I have read about that bus ad & the legal fight it took to be able to exercise our First Amendment right to display it. Jew-hatred has been hardwired into Islam for over a millennium, but the savagery of the current version has its roots in the Muslim Brotherhood & the alliance between Hitler & Haj Amin al-Husseini.
Only, how long before D.C. Transit buses with that ad are vandalized? CAIR will of course counterattack with their usual lawfare against criticism of Islam.
BTW, Mein Kampf in Arabic has been a bestseller in the Middle East ever since the Nazis had it translated in the 1920’s. Yes, 1920’s.
