As the extreme far-right AfD party repeatedly gets called out in German court for crimes including trying to diminish horrors of Nazism, the Guardian has posted a new first-person account with incredible detail of the pain and suffering from fascism.

Maxwell Smart still feels at his safest when it rains. The 93-year-old first learned this as a boy of 10, alone in a forest, lying on a bed of leaves in a makeshift bunker, waiting out the Nazi occupation of Poland. For two years he hid in the forest, evading hunters. Detection meant likely death.

“It was a sport to kill a Jew,” he says. “[Your typical Nazi] is not going to go in the mud and get dirty and filthy; he is doing it for happiness, for enjoyment. So when it was raining, I knew I was safe.”

When Elon Musk jokingly pals around with his AfD contacts and other extremist far right-wing hate groups and accounts on social media, one has to wonder if it brings him happiness, or enjoyment. Here’s what lies just behind such droll exchanges.

One day a notice was given for all Jewish men aged 18-50 to register for labour. Smart’s father was ordered to the town square along with 350 others. His father told him he’d be right back. On the square, the men were separated into two groups: one for professional workers (doctors, lawyers, teachers); one for skilled tradesmen. The professionals, including Smart’s father, were taken to a nearby hill and shot. Smart did not find this out until many years later.

The families were told that their men would be released if they relinquished their assets. “I remember my mother went to borrow money to pay them off,” he says. “It was all just a story. They were already dead. They collected the money but I never saw my father again.”

It’s extremely harrowing tales like this that beg the question why Elon Musk on Twitter (and with orchestrating the purchase of Twitter) has generated a reputation of being heavily and personally involved in promoting extreme right platforms around the world. Here’s what that really means.

In one Gestapo raid at the apartment his family shared with others in the ghetto, his grandfather was shot in the head right in front of him. “I could not really associate myself, a nine-year-old boy, with death,” he says. “I knew old people died, but I didn’t even think that it was possible to kill. It’s only when I saw that in front of my eyes I realised they were murderers.”

The family were imprisoned and the next day, they were violently herded into trucks. His mother told him to run.

“I was angry,” says Smart. “I said: ‘What do you mean you don’t want to take me? You are my mother.’” He followed her until she pushed him away and boarded the truck. “This saved my life,” he says.

Smart knew he would be shot if he ran, so he removed his Star of David armband and walked away until he reached a bridge, where he saw a German officer walking towards him. “He takes out the gun, points it at my head and he says to me: ‘Tell me the truth, are you a Jew?’” Smart denied it and somehow the officer believed him. “I am not a religious man,” he says. “But I believe it was a miracle.” He never saw his mother and sister again.

There is so much more to his story, one that obviously needs to be told again and again especially given recent AfD news.

…of the 8,000 Jews who lived in Buczacz, fewer than 100 survived. “I am one of the 100 and I kept it a secret,” he says. “I should remember. I have to remember. I have to tell it to the world.”
