i quote, "..Its also so rude to walk into someones house and call the hosts arrogant etc. So why do it over here with their country?"

a point well explained. hmmm, but i think if ure using metaphor here..one should also say "be kind to the guest". why i said this if you may ask, japanese people IN GENERAL are so courteous you'd be half amazed. theyre especially very accomodating, warm, and friendly to foreigners.
my say on this thread? "if one has nothing nice to say..ye shall shut up. :)"
its this, if you said something not nice in public..someone will definitely bash something not nice back atcha. okay, nice is becoming too redundant. by the way, people generalize all the time. its a fact. uve commited this "rudeness" at least once in ur lifetime. if he generalized in a good way, almost no one would bash at him because its a good opinion, right?
i guess he should say why some qataris are rude..not arabs in general. my arab friends are not rude!
