That's not at all true. We value the Constitution but remember that such as it was in 1789 it really only protected the rights of male white Protestant land owners as that is who made up almost all of the Founding Fathers.

There are beautiful ideas of human rights in the US Constitution but these should apply to any human being who has US citizenship among others as well. Gays, lesbians, refugees fleeing worn torn areas as well as various others leaving for a variety of reasons or who have valuable skills, transgenders, Native Americans, the mentally ill either labelled correctly or not, women, African-Americans, Hispanic-Americans, Asian-Americans, etc. should have the same fundamental rights that were given by the Founding Fathers to the very small class that the Founding Fathers were a part of. It is called Progress.
