America is the one of the few countries that protects minority rights through our political system. Most democracies do not have a mechanism that protects the rights of minorities through the power of the filibuster, federalism, and the ability of different political parties to control different branches of government.
We also have a Constitution which protects additional rights, that can not be questioned by Congress or the President. Congress has two branches, the House and Senate, drawn from distinctively different constituencies. It also have a separate executive, the President, who is drawn from a national constituency. Unless all these diverse groups agree, no policy can be implemented.
Most countries allow their governments to engage in rash decisions, allow a simple majority to act in a tyrannical fashion. Fortunately, America is globally unique, and and we restrict the power of the majority by empowering minorities. This is one of the reasons why America’s democracy has outlived most other countries, and has proven to be a stable, long-lasting form of government.
