Uh, Michele? About that last sentence? Yes it fucking did.
I don't know if you ever heard of this, but some of the people who came here, like, say, the First Lady's ancestors, came here as slaves. And even when they were freed, they were subject to great restrictions on their civil rights, and had to work hard to be treated as something approaching equals to white people. And true equality is still nowhere close.
Then there's the people who came here voluntarily. Like the Irish. Or the Italians. Or the Japanese. Or perhaps the Chinese, to whose immigration Congress was so indifferent, that in 1882, they passed a law to stop it. Or, God forbid, the Mexicans.
The USA is a pretty damn nice country to live in, don't get me wrong, but we've had problems in the past. Ignoring them won't help to fix their legacy, nor will it win you much sympathy with the people who have to deal with that legacy.
America is not perfect. Stop pretending that, and start working on something that could actually help with anything.
Love and kisses,
