Indeed, it is impossible to be un-American. America is a nation based on the free marketplace of ideas and concepts, hopes and dreams. America is a nation based on the ideal of liberty and freedom proverbially marching side by side with opportunity and equality. To be different is not to be un-American.
Difference is the essence of the American people.
America should recognize differences, physical and political, and embrace them. America is a strong and beautiful nation rooted in the soil of discontent. The founders of this nation dissented against the English Crown and fought for what they believed in. Their dissent is legendary, not to mention the basis for patriotism. Members of the women's suffrage and civil rights movements of yesterday and the gay rights movement of today fought and continue to fight for the rights of under-represented, marginalized people who were and are still left by the wayside because of their differences.
