Liberty and democracy are two different things. Only in the magical dreamy P.C. worldview the "good things" like tolerance, democracy, freedom, diversity, peace, justice, prosperity etc ... they "must" go together by nature.
Democracy/republic is about popular participation in government. Freedom is the ability to act freely, especially to live virtuous life (as opposed to licence).
You can have popular democracy making a lot of opressive laws and regulations or you can have a monarchy with very limited government and people living as they wish.
You have been smoking something. While of course this is true in theory, in practice do you honestly beleive that it a benevolent monarchy can be sustained?
There is no doubt that democractic societies are capable of oppression, but there is no superior way to achieve liberty when you take into account the realities of human sin. Constitutional protections help but they will only take you so far, particularly in a society with such an overwhelming majority (Islamic) like in Iraq.
Well siad. Too many so-called "conservatives" today fail to grasp the fact that democracy is only a means to an end, and sometimes it is not the best means.
