Check out the graffiti on the 8th Avenue AFDI ad. Do these maroons know they are reinforcing my message? The calls to jihad in the quran are war propaganda. The calls to "slay the pagans wherever you find them" (9:5, 2:191, 4:89); the call to make war against and subjugate the People of the Book (i.e. Jews and Christians and Zoroastrians -- 9:29) -- that's war propaganda. 20,240 jihad attacks since 9/11 were motivated by that war propaganda.
And how much does it cost to remove this graffiti? I am sure these thugs don't pay the taxes required for remove. It's the jizya, baby.
