GTFO to where? This used to be the "where" for people all over the world.
Yep. And that was fine when we welcomed those who embraced our culture and values and ethics, those who wanted to *be* Americans.
Then, along came the Left who decided that putting our own self-interest first, by welcoming those who wanted to BE us, was discriminatory and unfair, the Left who decided that, because what we were enabled us to build what we had, it obligated us to
share "the wealth" we had generated, that we needed to become the world's pocketbook and jobs market, that America should henceforth be run for the benefit, not of ourselves, but of the alien other.
Upon reflection, that this point of view has infected so many of "us" is not surprising. If "we" were commanded, mandated, coerced, and forced to consider and support first and foremost "the other", they simply became the home-grown other.
