Who replaces whom?

If we were to apply Snarlson's 'logic' he and his sick ilk should be the ones to go. Fortunately an original American value is inclusion, at least theoretically in the Constitution. It took a while to implement some of that inclusion like for women and people of color. And we still have a way to go. 

But Snarlson's replacement theory is exactly what original American values fights against. We fought a revolutionary war against England to get rid of that sort white racist nationalism and aristocratic caste system. And we refuse to go back to it by defending democracy: "One nation, indivisible, with liberty and justice for all." 

In other words: F___  off Mucker.
