Every time you see or hear any encouragement to continue division in America, you see or hear our common enemy. America has everything needed to be safe, happy and free. Anything that works against that is attacking us all. Humanity has always been full of errors. Yet, we have clawed up from simple survival to tall towers of knowledge, wisdom, compassion and enlightenment. The ominous shadows of our limited past still cause fear, but we are almost to the point where we can all be free of it. Every binary, divisive urge is one that would hold us back, or, worse, seeks to plunge us back into the past. If you want to destroy our Republic, continue with a divided mindset.
You are willing to declare parts of the country "our common enemy". In so doing, you are creating the deepest division imaginable. According to your own line of logic, you are the enemy. That line of logic currently serves to create the kinds of "illiberal democracies" in Brazil, Hungary, and Poland, and it appears to have arrived in the U.S. of A. as well.
Unity, if desirable at all, has to have a foundation in the form of Constitutional guarantees of inclusiveness, centered on equality. That's the only way to forge one entity out of a staggeringly, admirably diverse population with points of view, aims and aspirations representing black and white and every shade of gray and color in between. By necessity there are going to be divisions, as there are in anything humankind creates. These turn toxic and deleterious insofar as one part declares itself the righteous and dominant one, and the other part(s) the enemy.
