Here are but a few examples of their handiwork. America was founded on the principle of equal opportunity for all individuals, not federally dictated outcomes for select groups. Affirmative action is un-American and will eventually die but not before doing great damage. Symbols are visual rally points that serve to unify. Throughout history, a key element in destroying any civilization has been to destroy the symbols of its culture thus dealing a significant blow to that unity and weakening the entire society as a result.
Mob action does nothing but widen the chasm in America.
Los Angeles, Watts, Seattle and Cincinnati come to mind and the actions of these agitators usually do more to stir up rather than clam down those involved. Hate Crime Laws. Laws that dictate unequal justice under the law IF you are a member of the legislatively designated preferred group is another example. I think the issue of reparations will deeply divide the country. There will be some that although opposing it, will say little if anything.
