In 1988, I was invited to attend the Aryan Nations World Congress, the annual pilgrimage site for far right elements from around the globe.

It took place on Richard Butler's remote compound in Coeur d'Alene, Idaho.

-Our media is owned and controlled by Jews.

So, the Jewish view of life is what we've been brought up from.

-Often described as the spiritual godfather of the white supremacist movement, Butler was part of a lineage that shared its roots with the German-American Bund of the '30s, the Bund that established youth indoctrination camps across the U.S. and famously packed Madison Square Garden 20,000 strong in 1939.

And later with George Lincoln Rockwell's American Nazi Party that threatened to march on Skokie, the small Illinois town targeted for having the largest number of Holocaust survivors outside of Israel in the late 1970s.

- And we will save the white race.

Sieg Heil.

-But through all of my trips to Aryan Nations in Idaho, the man who made the strongest impression was Louis Beam, a powerful dynamic Vietnam War vet.

Hardcore in his beliefs and uncompromising in his actions, he would become a decisive role model for me.

- Our enemies own and control this country.

They control the communications.

They control the media.

They control the police and the government.

-Beam had created the Aryan Liberty Net, the first use of computers to organize white supremacists and disseminate propaganda, the strategy I would come to embrace as well.

Inexpensive, difficult to prosecute, and with a powerful reach, the early adoption of technology would become a cornerstone of spreading racist propaganda.

It's not hard.

Where there's a will, there's a way.

When opportunities present themselves for me to do other things, which I think will be effective, I'll be in there like a dirty shirt.

Following the FBI takedown of the order, and his own sedition trial, Beam kept his distance from any activity that might land him in jail.

Instead, he began to advocate for leaderless resistance, acts that could be undertaken by cells of one because cells of one can't be infiltrated.

With Beam underground, I followed his lead and example, putting my own burgeoning computer skills to use to create a Canadian-based Liberty Net.

You have reached the Canadian Liberty Net for Sunday, August 21, 1994.

But in the law of unforeseen consequences, what began with crude online bulletin and message boards would see its full and dangerous potential realized decades later through the increasing sophistication of the Internet and social media.

Technology once used to find and disseminate information is now used to find and create community, a shift in paradigm that has sparked horrifying acts of violent extremism.

I encourage people when they're in the military to keep a very low profile.

Disrespectful is too nice a word.

Prior to the gas chambers and crematoria at Auschwitz, roaming death squads had killed more than a million Jews across Germany in the occupied territories.

In what's been referred to as the Holocaust by bullets, Jews were shot and burned in crude open pits or killed in experimental gas chambers using farmhouses or mobile gas vans.

But the Final Solution required a more efficient and mechanized process of extermination.

Auschwitz would evolve to become the largest of six industrialized killing centers developed in semi-rural, isolated areas in the occupied territories hidden from public view.

Their strategic location along major railroad lines allowed for the expedient transport of hundreds of thousands of prisoners directly from the ghettos of Poland and Hungary.

Can you share with me what each of the rooms was?

-So long, narrow room with openings in the ceiling -- this is the gas chamber.

The next room, this is crematorium.

First of all, building worked as crematorium.

The burned bodies of those who were murdered in the camp, who were killed, were executed, who starved to death.

That in 1942, that long narrow room became the first gas chamber here.

Originally an ammunition bunker, then a morgue, it was adapted into a provisional gas chamber and the first furnaces for burning corpses installed.

Mired in the misery of a deep European depression, with unemployment skyrocketing as high as 40%, Germany was also reeling from an influx of immigrants as over a million and a half refugees, many of them Jews from Eastern Europe, poured into the country after the devastations and deprivations of the Great War and the Russian Revolution.

In anti-Semitism, Hitler and the populist German political right found a convenient scapegoat for a complicated set of ills.

Looking to assign blame for the humiliations of the Treaty of Versailles, the conspiracy theory arose famously known as the "stab-in-the-back," pinning Germany's exit from World War One on the Jewish political elite.

Simply put, Nazi ideology and the promise to restore German pride with sloganeering that vowed to "make Germany great again" was the answer to every dimension of its perceived vulnerability to the world.

-[ Speaking German ] -This is not, of course, an excuse for the horrors that followed, but does provide an understanding of just how easily vulnerabilities can be manipulated and polarization fueled.

Let you into this moment and into this place for some reason.

♪♪ -Oh, I can guarantee you this journey doesn't end here.

♪♪ ♪♪ As recent trends have sadly underscored, anti-Semitism and other forms of hate are not likely to disappear on their own.

And the echoes of the Holocaust reverberate whenever people regress to scapegoating, polarization or dehumanizing and divisive us-versus-them camps.

And this exploitation of unfocused rage channeled into issues around identity, immigration, and race continues to fuel these fires today around the globe.

♪♪ Lest we forget, the Holocaust isn't the last time we've seen large scale campaigns of genocide or mass atrocities in the modern era.

♪♪ And the grim reminders of what humans are capable of continue to surround us today.

♪♪ ♪♪ ♪♪ ♪♪ The true value in my story, and why I continue to share it, is that if someone like me can find my way back to humanity, someone who was once so disconnected from the humanity within themselves, then perhaps anyone can.

♪♪ My hope today is that stories like my own can somehow help young people to retain this humanity and maintain their sense of compassion, because compassion for oneself as well as others is the only true cure for hate.

♪♪ Our lives and our history are filled with lessons we can't afford to turn away from, lessons we can't afford to forget.

Auschwitz had long loomed as a symbol and a reminder of the hateful legacy I once espoused.

Now it has become my teacher.

There's a power in bearing witness on its grounds that can't be put into words.

But Auschwitz is also a container for profound lessons, lessons perhaps as important as ever as the echoes of history continue to reverberate around us.

♪♪ The inescapable truth is that white supremacist ideology, if left unchecked, always ends in murder.

And keeping the lessons of Auschwitz and the Holocaust alive is a way to help ensure it never happens again.
