An interesting series of responses, KOYAANISQATSI.
I don't "look at the world through the cultural Marxist lens of victim and oppressor" or "[live] in the mainstream media's, leftist bubble echo chambers", and I don't believe I have a "regressive narrative"
I can, however, read, and when the President of the USA tweets "Why don't they go back and help fix the totally broken and crime infested places from which they came" about US citizens who are also democratically elected representatives, and chants of "Send them back" ring out at a subsequent Trump rally, then the racist alarm bells ring. No media bias, spin, fake news or subscribed narrative required.
Maybe Trump isn't racist and was just trying to go on the offensive with whatever came to him, maybe he is naive and didn't consider the consequences of repeating such classic racist tropes, and maybe it's a co-incidence that such statements act as a rallying call for the right leaning side of the spectrum. Or maybe he knew what the likely outcome would be.
