“For we know that our patchwork heritage is a strength, not a weakness. We are a nation of Christians and Muslims, Jews and Hindus--and non-believers.” He has placed our successful AND peaceful way of life and Spirituality into the category of “Non-Believers!”
Then he uses the phrase “the lines of tribes shall soon dissolve.” What does he mean? Certainly, NOT the tribes of Israel. Who, but the American Indians are referred to as Tribes? We are the ONLY ones.
Obama’s “Final Solution” to the centuries-old “Indian Problem” is total dissolution.
But still, Obama could've found a better way to phrase this passage. He could've guessed that someone might think he meant there are only five belief systems in the US. Obviously he wasn't presenting an all-inclusive list, but it's best not to leave these things for literalists to (mis)interpret.
Means's second point is more on the mark. Obama's comment about "tribe" (not "tribes") was insensitive at best. Few people are aware that there are tribes in places such as Iraq, Afghanistan, and Pakistan. If you gave Americans a word association test, I'm guessing about 95% would respond "Indian" to the word "tribe." America's Indian nations are the most famous political groups known as "tribes."
