Comment: Of all the "western societies", Japan doesn't seem to have a Muslim terrorist problem.  This is because they DO NOT ALLOW the immigration of Muslims.

Sorry, but terrorism is "baked into" that religion, and the Japanese know and understand this.  They don't consider it as being racist, they consider it being common flipping sense.  

When their holy book (the Koran) specifically instructs its followers to "kill the infidels", there can be only one eventual outcome (murder via terrorism).
