On the Fact that the United States Is the Most Successful Multi-Racial Country In World History but Because it Doesn't Mesh with Their Utopian Fantasy Notions the Radical Left Continues to Portray Us as this Racist Hellhole

 Obviously a lot going on here but I'd say that the two main factors are a) a political class that's ultimately discovered that pitting groups of people against each other is an excellent way to solidify power (through distraction and the creation of new special interests) and b) a higher education system steeped in Marxist dogma that's been poorly educating people for multiple generations now (to the point where we actually have woke jerkoffs running corporate boardrooms). And it's all coming to a head, as you can see.
