No need to get confused,actually ya-akhi,many people have complained about saudi policies,some had bad experiences while working in middle east ,they complain of treatment,every nation has good and bad people,for example racism can still be traced in Britain..
Also,many have expectations with Arabs due to past record,that Arabs can take bold steps and can appear as 'role model of strength' but when they saw the Arab regime supporting US,their feelings are very much similar to that of Afghans who react to see Pakistan supporting US against war on terror.
But they don't reveal it comfortably,generally speaking,they try to keep it with themselves,thus as a result of which you can see their response as aggressive and uncomfortable.
Ya-akhi,many seem to hate/dislike/criticize you because they don't like to see you supporting US etc,I am saying this to you,because I am sincere and I want to use this forum to help each other of you to listen the actual voice rather then derailing the thread,trust me,tomorrow,Saudi will take any bold step,these people will be first to congratulating you,it is just that,their criticism is transforming into aggression due to improper communication,if misunderstanding persists,then I am afraid,that you people will hate each other one day.
