On Millions of Dirt Poor, Undereducated, and Unvetted People Breaking Into a Sovereign Nation and Promptly Throwing Themselves On the Mercy of its Welfare System Which Was Intended for the Individuals Who Reside There Legally and Whose Tax Dollars Prop it Up - This is unprecedented in world history and largely happening because of two factors, a) the Democrats bleeding votes among multiple constituencies and hence desperately needing reinforcements and b) an education system that has immersed itself in hardcore crap like Postmodernism, Cultural Marxism, and Intersectionality. Yeah, there might be a few other causes but in my mind this is the cocktail that brings it all down. Ultimately.
