The experience of life under British rule has created an extremely sensitive nation from the American nation when democracy and the rule of law are in question. The experience of unlawful taxation as well as the absolutist attitude of the monarchy embellished the Americans with repulsion towards every apslotism, as can be clearly seen from the Declaration of Independence. The right to vote, the rule of law are things that the Americans first notice if they are violated.
