Not quite. Racial groups tend to cooperate for a common good when the rules are the same for everyone. Elites change the rules to create division. We are witnessing the result of chaos spawned by elite cadres of globalists who need national chaos to bring the nation to heel.
***Not quite.***
A “celebration” of diversity and multiculturalism in the American population was introduced in the 1960s and 70s as a deliberate, divisive revolutionary tool wielded by Marxists like Saul Alinsky, Bill Ayers and other radicals. It became dogma taught by Marxists in our universities, then spread by our leftist controlled news media and leftist controlled Hollywood. The intent was, and is, to split American culture along race and class lines and set off a “proletarian” revolution to destroy capitalism. The Left has now managed to elect a half-Black radical as President and their revolution is proceeding along very predictable lines, with him using every opportunity to stir up more division and discontent. A reading of the Constitution of the Revolutionary Communist Party, USA at this link should make clear their goals and methods: http://revcom.us/Constitution/constitution.html
