What I admire most about the United States of America is its potential. The Declaration of Independence, Articles of Confederation, and Constitution may not have been written with everyone in mind (the Founding Fathers kept slaves, after all) but U.S. principles have the potential to include and invite everyone. Those who don't have equal rights should continue to fight to be recognized.
