Editors from English--speaking and European countries do operate under more or less the same ethical system, which promotes freedom and fairness [..]
That is untrue. One of the working principles of the arbcom is that it does not want to be fair to editors, but to make decisions that will help the project. This was explicitly written down by arbcom members Flonight and Charles Matthews. I hence decided to follow their example of not trying to be fair to others in Wikipedia.
