If it's personal encounter, than you better not generalize and say A LOT!
I've been tracking xenophobia in our society for the past 4 years. while there is huge feeling of resentment among conservatives over women dress code & the less fortunate Qataris over westerners higher salary packages, this have never developed into hostility. Even with other Arab/ south asia expats, it's that ethnic , tribal, & sectarian barriers, that I wouldn't consider it a large scale xenophobia. As it's concentrated among the less educated.
