A Look at Neo Nazi Content Growing on Substack

Substack presents itself as a haven for independent writers, but its minimal moderation has allowed openly neo‑Nazi newsletters to flourish, including one that glorifies Hitler, denies the Holocaust, and calls for genocide. What I found while investigating a smaller antisemitic account raises urgent questions about how far “free expression” can stretch before it becomes a shelter for violent hate.

This article contains explicit examples of antisemitic and neo‑Nazi rhetoric taken directly from a rapidly growing Substack newsletter. I include them not to amplify hatred, but to expose what is being published — and normalized — on a platform that claims to champion independent thought. Some of what is shown is disturbing. That is precisely the point.

A recent post on the Substack newsletter NatSocToday ends with an open call to smash the Jews, promising genocide “next time around.” No code words. No euphemisms. Just raw, unfiltered hate:

We will smash the jew, no mercy of camps this time jew. No. Mercy.

This is not an anonymous Telegram channel. It is a Substack account with more than 500 subscribers, created in February. It glorifies Adolf Hitler, denies the Holocaust, and promotes exterminationist antisemitism under a thin veil of First Amendment rhetoric.

The Free Speech Dilemma       

After I published my article about Graeme Bird — a fringe Substack writer who hijacked my Note about abducted Syrian women to spread the classic antisemitic trope that Israelis/Jews traffic in organs — one reader argued that people like Bird should be mocked, not reported. Let them rant, he suggested, and let their own delusions expose them.

Mockery has its place. Exposure matters. But what happens when these ideas don’t stay isolated? When they grow quietly, algorithmically, unchecked? Substack prides itself on free expression. But freedom without limits can become a home for hate — and eventually, a vector for violence.

When a platform allows openly genocidal propaganda to flourish, can it still claim neutrality?

How I Found NatSocToday

I didn’t go looking for neo‑Nazi Substacks. I was following up on Bird’s account, which has about 50 subscribers. Among those mostly Jew‑bashing followers, I found NatSocToday — and realized immediately that this was something different. Something organized. Something growing.

The content is not subtle. It is designed to provoke, dehumanize, and radicalize. It claims to promote:

...the peaceful return of traditional White nations to the native White populations who built them.

This is not political commentary. It is incitement. It is a threat. It is a call to genocide.

This Isn’t Fringe — It’s a Community

With more than 500 subscribers, NatSocToday is not a lone extremist shouting into the void. It is a community — and community is exactly what Substack promotes as one of its core strengths. That is what makes it dangerous.

We don’t know whether these subscribers arrived as part of a coordinated ideological project or were drawn in after the account became active. But what we do see is clear: an effort to reframe Nazism as a legitimate political identity, to sanitize genocide as “ethno‑defense,” and to recruit others through repetition and false legitimacy.

Substack’s low moderation and “let the market decide” ethos have created fertile ground for accounts like this.

I am not calling for censorship of difficult conversations or for banning criticism of Israel or any other contentious issue. I am calling for platforms to recognize when they are being used, when the principle of free speech is being hijacked rather than respected.
