Well done Yahya,
I also would suggest that people should have a positive attitude towards the society they're living in.
It's a good thing to make friends,think of ways to make friends here in Doha,socialize rather than keep complaining about life and people here.
Arrogance is a very crucial thing when you try to deal with,if you attack it you might just provoke it more and more.
The best way to fix arrogance is by trying to address the reasons why this someone is arrogant.
Somepeople are arrogant because they have better degree or certifiocate than you,others are arrogant because they have more money than you,others are arrogant because they come from richer countries even though they might not be worth trash but still they are arrogant.
So one needs to diagnose the reasons for arrogance before criticizing it.
I beleive the arrogant Qataries you are talking about are the most benign type of all,simply because all they need is just little respect and education.
Many expats come to this country and think of Qataries as a bunch of camel riders who have just became rich all of the sudden...well,even though this might be a true fact yet we need not to address it with an enveying heart,just be happy for them and start thinking how we can help them best use this money to build a civilization.
Don't forget that many Qataries are very highly educated and very well brought up,but again expats don't want to acknowlege this fact because it is a sort of threat to their careers.
I think it is just a Tea-Time conversation when the Karwa official said "ALL" felons or abusers are Qataries,my advice to you is whenever you hear the word "ALL" from someone,know that this person knows nothing about the issue.
Good luck to you all
