Former Texas Representative Ron Paul tweeted a wildly racist image of minority groups uniting to punch Uncle Sam.

The three-time presidential candidate deleted the tweet, but by then Twitter had already immortalized it.

The tweet read: “Are you stunned by what has become of American culture?” Paul said in the tweet. “Well, it’s not an accident. You’ve probably heard of ‘cultural Marxism,’ but do you know what it means?”

The image covered most of the bases as far as horrendous racial tropes go: The African-American man has hugely inflated lips, the Asian man's eyes are slits while his teeth are exaggerated, and the Jewish man's nose is elongated and hooked.

Ron Paul later replaced the image of the tweet with an image of "Political Correctness" obscured by a "No" sign. Americans have been quick to remind him that his vigilance against what he perceives to be a society obsessed with political correctness is just what got him into this mess.

Paul's deleted tweet echoes with something far more insidious than can be deleted with the swipe of a finger. 

Many Americans have compared the actions of the current administration and those acting under its umbrella to the rise of Nazi Germany. While this argument is not new for any administration, it used to be far more easily dismissed. Suddenly, for many Americans, dismissing this argument has never been so difficult.

From President Donald Trump referring to neo-Nazis and white supremacists as "very fine people" after the catastrophic Unite the Right Rally last year to the recent victory of Trump's travel ban in the Supreme Court to the murders of five journalists at the Capital Gazette (which many attribute to Trump's constant vilification of the press) to Ron Paul's tweet with propaganda not unlike the kind used to vilify the so-called undesirables of 1940s Germany, Americans are sensing historical reverberations with nearly every new development.

Ron Paul's tweet is just another example of how emboldened these sentiments have become in just the past three years. It's telling of how far things have devolved when a seasoned politician like Ron Paul can see racist propaganda and believe it acceptable with the masses to spread an agenda.

But unlike Germans of the 1940's, we should be able to see it coming.
