akhi, would you agree with Al-Sudais in condemning the protesters in Tunisia, Egypt, Saudi, Bahrain, Libya and Syria who wanted to overthrow their oppressive, brutal leaders?

After all, it is unislamic to 'disobey' your leaders?

You're mixing two issue in such a way that it's wrong to reply with either "yes" or "not".

It's unislamic to disobey your leaders until they remain into the folds of Islam and don't command you to commit some sin.

But if they are apostate tyrants, it's permissible to disobey and revolt against them.
The issue is deep and there are various conditons and so on.
The point is that we can't apply the Islamic ruling of obeying leaders (which goes against anarchy etc.) to the present situation of kuffar tyrants being leaders of most of "Muslim countries".
