False. A Republic, by its nature, is guided by a constitution, such as ours which protects the rights of individuals and minorities.
By that definition, Denmark and Norway, both monarchies, would be republics.
Democracies have no such constitutional requirement, allowing them to trample on the rights of individuals and become tyrannical.
Which countries do you have in mind?
Gosh, people really seem to be misunderstanding my point. Republics are not the only form of government that allow for constitutions, but they are one of the only forms that, by definition, require one.
Again, where do you get that impression from? In its strictest definition, a republic is just a government by popular election.
