Is democracy is situable for all citizen?

Answer 1

That is the question, isn't it? Certainly, you cannot simply and quickly force a nation to embrace democracy, any more than you can force it to do anything. The assumption often is that if the majority of people in a nation are oppressed and even badly abused, and if they want a change that they cannot seem to bring about, then democracy is a system that they should be free to try. But that has to be tempered by the reality that nations are sovereign states and can follow, within reason, the systems that history, traditions and the popular sentiment deem correct. The idea of 'forcing' democracy is contradictory. The other thing that has to be tempered by reality is the assumed legitimacy of oppressive and absolute theocracies that engage in atrocities against humanity in the name of a deity. Such theocracies concentrate all power and authority in the hands of a very few men who usually operate beyond the scope of any civil law, and certainly beyond the authority or control of the people governed. This is abhorrent to the minds of most who understand democracy, but even these systems can be part of the operations of some sovereign states.
