The problem lies in a false religion that demands it's spiritually twisted adherants (aka captives) follow the most stringent, legalistic religious rules in the world while simultaneously demanding they make all other uncooperative people either similarly twisted adherants or dead!
The hospitality thing is a real fact about desert culture, including the Jewish culture. Look at Lot in Genesis 19-1, he protected his visitors to the extent of giving away his own daughters!
Arab culture and civilization before the fanatic Islam took over these people was a nice and friendly culture. Our problem now is that we looked the other way for about thirty years as the Arabs leaderships was accelerating downhill into the pits of barbarism. The liberal idiots in Washington kept reporting: that is not our problem, we support freedom of religion, and if that is their religion, we should simply respect it! I cannot respect any religion or any God for that matter that is preaching hate and violence against me! That is the end of my tolerance! At this point, we have generation of Arab Moslems that Hate Jews and Christians. It is going to take a minimum of quarter of a century of BRAVE LEADERSHIP in the west before we can rehabilitate this culture back from the stone-age to the civilized world. For now, however, we should close our doors to any more Moslem Arabs.
