One way you might address the question is to first differentiate between political ideology from political reality. For example, when the framers of the Constitution chose the aspiring ideological words We The People... in 1789, in reality it meant white, male, twenty-one, and property owner. Now you could begin to answer the question by stating that although the struggle for freedom and equality in the U.S. was met with discrimination against African Americans, women, post Civil War immigration, and violence, the nation has clearly moved towards the aspiration of freedom and equality for all. In order to support this answer you must include specific examples. I offer these suggestions: (Be sure to elaborate on whichever ones you choose to include in your answer)
1. Amendments: 13, 14, 15,19, 24, 26
2. The Civil Rights Movement: Brown v. The Board of Education 1954, The Little Rock Crisis 1957, The Civil Rights Act 1964, The Voting Rights Act 1965, Affirmative Action Legislation, Americans With Disabilities Act 1990
3. President Johnson's Great Society programs, among them VISTA, Mediaid, and Medicare, Food Stamp Program, Elementary and Secondary Education act 1965
The United States is not without fault with regard to 'how' to achieve the aspiration of equality and freedom to it's citizens, but in my opinion the Congressional legislation, past, present, and future, the Supreme Court decisions that have moved our nation towards freedom and equality, civic duty, and the majority of Americans' deep rooted belief in the idea of We The People... however difficult it is always worth any turmoil if the end result is the ever evolving, ever lasting importance of freedom and equality....Life, Liberty, and the Pursuit of Happiness...
