It's laughable that we declare a national holiday in the name of one individual and nearly every private institution is cowed into observing it. But, that flows right along with all of the other ridiculous political correctness we're forced to tolerate every day.
I don't understand your over-emphasis of the word, American, but the values that I hold dear are embodied in the Constitution of the United States of America. And, frankly, I am totally uninterested in how those values benefit anyone who is not a loyal citizen of this great nation.
