It is relevant because you can not hold a grudge on an entire region of the world for a single event, no matter how horrific. I mean if you want to bring up the holocaust, maybe we should still be persecuting and barring entry to all Germans of the slight chance they are extremists? If you want 9/'11 included, perhaps we should the # of Americans that died in WW2 and the race of those who killed them.
anyone can make cuts in the data to fit their narrative, don't be ridiculous.
