Personally, I'm not scared of Qataris and have awesome Qatari friends, actually one of my closest friends is Qatari. I think it's the "first move" that might seem scary to some because of language barrier (for some), cultural differences, social status (afterall foreigners don't have the same rights as Qataris), etc but once u get to know them, they're pretty cool and down-to-earth, ofcourse there will always be jerks like Oryx's experience but hey that's in every country.
