William"  You present the very old "America, love it or leave it" position.  That's hardly conducive to constructive discourse.  To exercise one's First Amendments rights and express displeasure with a specific facet of American life is hardly to disgrace our country.  You see someone exercising those rights in a way you don't like, presenting a position you dislike and, presto, you suggest they should leave the country.  Frankly, sir, I find that far more "unAmerican" than "taking a knee" to protest police violence toward black men.  However, being a very nice guy, I won't suggest you should leave the country.
