Your hyperbole about 'fundamentally changing the fabric.....'is just that and even if it were accurate it would be a subject for debate and not worthy of xenophobic racist remarks.
When you get on Jeopardy be sure to say "False Equivalence for $500, Alex."
BTW, if Trump had said to a congressman from Serbia who always bitched about the country and whose policies were geared to fundamentally change the fabric on what this country was founded on, would it have been a racist tweet?
