There is good and bad in every society. However this is a historical fact that Arabs in general are a very proud nation and consider themselves superior then others. This why my lord and master Muhammed(SAW) clearly said in his last Khutaba that no Arab is better then Ajam and no Ajam is better then Arab. I my self am a resident of GCC since last many years. And while I have seen some very gracious and kind Arabs, yet mostly my feeling has been that they treat others, specially Asians with not so much respect.
May Allah guide us all to live with utmost respect for our fellow humans irrespective of our color, creed and race.
