My grandfather spent his entire life after the Holocaust trying to mitigate its damage: confronting the things you hate the most, the realities that crush you, give you purpose. For my grandfather, that meant helping Holocaust survivors situate in the United States. He helped found Yad Vashem, one of the most decorated Holocaust institutions in the world. On the day of his funeral, the absolute and unequivocal respect of his colleagues, friends and his family was completely ineffable.

It’s the things that crush us that become our proverbial bat cave. Everyone’s got a choice; you get to either be Bruce Wayne or Batman. You can run away from trauma, or you can headbutt it squarely in the nose. This was my grandfather, he had never unclasped his grip on the Holocaust, and that made him an incredible force to be reckoned with.

Socrates put it the best when he said, “From the deepest desires often comes the deadliest hate.” People find inspiration in the most unusual and, in this case, horrible ways. Germany was obliterated after the World War I, and the country itself experienced trauma. People were burning money in their furnaces for warmth, and there was a sense that German pride had been indefinitely tarnished.

Adolf Hitler was their promised redemption. He was a charismatic man, full of promises and subversive literature which was popular with the youth. When the Nazi Party took over, Hitler was quick to answer the “Jewish question”. He summoned his leaders to the Wannsee Conference in 1941 where they laid out an extremely elaborate plan to exterminate most Jews and use some to labor before killing them too.

What made the nationalism of Hitler’s Germany so terrifying was the way an act of genocide could be spindled out of an act of kindness, even generosity, for one’s country.

The general public maintains myths to rationalize atrocities like the Holocaust, like that fear and authority drove Einsatzgruppen soldiers to line up Jews and shoot them and then rolled them into ditches. But Himmler insisted that once they began the extermination, they could not let any Jews live on the basis that their search for vengeance would be the utmost threat to Germany. He urged his soldiers on multiple occasions to consider the world their children should inherit. It was not a pistol against to their heads which drove ordinary citizens to enact the Holocaust but rather Himmler’s Macbethian “too-far-to-go-back” rhetoric.

The idea of having gone too far to go back is not exclusively to Nazism. Today in America, there is a culture of acceptance in regard to racism and intolerance and perspectives fostering a perception of difference, by race, sex, religion and gender. It goes to show that no matter how “westernized” or “progressive” a society is; it may be impregnated by the seeds of division, and subsequently, mob mentality.

The tar of Nazism essentially met the slipstream of modern internet-hate. Combined, the American Nazi has become a cancer cell that has metastasized into everyone’s backyard.

In fact, the United States is becoming an increasingly hostile environment for Jews. Battery and assault from this trendy new anti-semitism is not simply from either the right or the left, but from every corner of American politics.

While the BDS movement to boycott Israeli products on college campuses are hostile and pose an identity conflict for many Jewish students, there is a far more dangerous spike in hatred from the right. The alt-right has produced anti-semitism in this country on an unprecedented level. From National Socialist lodges to the Internet to marching on the street with tiki torches, the culture of hating Jews is spreading.

4chan is a petrie dish of American society—he extremes of many concepts spread their roots and grow in fertile soil. For the alt-right, the fertile soil is the population of cloaked patrons who make a hobby out of hating Jews. On the board /pol/, they dubbed “redpilling”: suggesting that they are shedding some invaluable truth hidden from “normies” or people not associated with the alt-right.

These trolls claim that Jews caused every war since World War II and that there is a Jewish “hive” mind with an established agenda. Whether or not these people truly believe what they say, we have seen that some, like Dylan Roof, believe what they read on the internet. In the words of a /pol/ 4channer trolling New York Times’ Jonathan Weiss, “MEME MAGIC IS REAL.”

If one understands that these jokes and antics can have deadly implications, why is it so hard to combat Internet anti-semitism? We underestimate the normalization of anti-semitism in our culture. How many people in your life go on 4chan on a daily basis? Likely none or not many. Through anonymity this movement has grown exponentially in the shadow that is the Internet.

There is something, however, that cannot be ignored. With the sheer quantity of Jew-hate on the Internet, it was only time before they naturally gravitated into some kind of cohesive structure: American Aryan and Nazi groups.

In the last few years, it feels as though Nazism has left history books and dispersed itself in the wind, stretching across the country.

The Southern Poverty Law Center reported nearly 900 acts of harassment and intimidation in the 10 days after Donald Trump’s election as president. Nooses have been hung in Brooklyn neighborhoods, a black college student attending the University of Maryland was fatally stabbed and even on the Cornell University campus, a black student was berated by racial epithets as he was assaulted by a group of white students.

These are only some of the names of the most imbedded, normalized Nazi organizations that have seen growth since Donald Trump announced his candidacy in June 2015:

• American Nazi Party
• Aryan Brotherhood of Texas
• Aryan Guard Aryan Nations
• Aryan Terror Brigade
• Hammerskins
• Heritage Front
• National Alliance
• National Socialist Movement
• National Socialist Vanguard
• National Vanguard

If you need to see what modern anti-semitism looks like, look no further than the 60 bomb threats made against Jewish centers across the country, in over 48 different locations and 26 different states, according to CNN.

The tar of Nazism essentially met the slipstream of modern internet-hate. Combined, the American Nazi has become a cancer cell that has metastasized into everyone’s backyard.

To come full-circle, consider this: nobody put a gun to the heads of adolescent trolls on the internet, nor did they put a gun to Dylan Roof’s head or to the heads of National Socialist recruiters who are currently swarming the internet. It all begins as patriotism which is warped and perverted into something much worse. It is based in scapegoat rhetoric, ethnic hatred and xenophobia. With the rise of Donald Trump and the popularization of anti-Muslim policy and cultural development, every sound-minded American should look at how easily one group of people can be slandered and driven away en-masse, and they should fear that.

For a great deal of Jewish Americans, that fear has already set in.
