Many organisations respond to challenges by investing in communications.

Far fewer invest in organising.

This article raises an important strategic question:

What if antisemitism is not primarily a messaging problem?

What if the more important work involves building stronger relationships, broader coalitions, deeper leadership pipelines, and more resilient communal infrastructure?

Communications can shape attention.

Relationships shape behaviour.

Infrastructure shapes outcomes.

An interesting and thought-provoking read:

For Rabbi Aharon Ariel Lavi, who lives on the Gaza border with his wife and five children, the events of Oct. 7, 2023, are deeply personal.  But, professionally, Lavi is particularly concerned by how the Jewish community responded after the Oct. 7 attacks — spending hundreds of millions of dolla...

Odelia Epstein’s essay Transforming Jewish Education in the Age of Artificial Intelligence is one of the clearest pieces we’ve read on the future of Jewish peoplehood education.

The argument is not simply that Jewish education should use more technology.

It is that emerging technologies can help us intentionally cultivate relationships between Jewish students across countries, communities, and contexts.

That matters enormously.

In an age where information is increasingly abundant, Jewish education has to focus more deeply on relationship-building, cross-cultural competence, and helping students understand contemporary Jewish life beyond their own community.

This line captures the challenge beautifully:

“The question is not whether it can be scaled, but if we have the vision and will to do so.”

Highly recommended reading for anyone working in Jewish education, campus life, youth movements, Israel education, or communal strategy.

I think most people, when they first encounter a clip like this, instinctively focus on what’s being said.

That was certainly my reaction when I first saw this video two summers ago.

Coming back to it recently - while working on my most recent essay - I found myself paying much closer attention to the structure of the reasoning itself.

Not just the conclusion being drawn, but how that conclusion is being held in place, even when it sits alongside ideas that would normally create tension.

I’ve found the concept of a “constellation of beliefs” to be a useful way of thinking about this.

Not as a replacement for other explanations, but as an additional lens - particularly when trying to understand how similar patterns of thinking emerge across very different contexts.

I explored that idea in more depth here:

Would be interested in thoughtful reactions.

This is one of the most chilling moments in Louis Theroux’s Inside the Manosphere.

Not just because of what’s being said.

But because of how familiar it’s starting to sound.

Different influencers. Different countries. Different platforms.

Same conclusions. Same language. Same conspiracies.

That’s not random.

It’s what happens when people are drawing from the same constellation of beliefs.

I think this helps explain something much broader about how antisemitism is spreading right now.

I wrote about this properly in my latest Substack essay

A new weekly dvar Torah, this time on Tazria-Metzora.

I took two weeks off posting. In that time, during Pesach, my wife Leora gave birth to our daughter, Odeya Miriam. Coming back to these parashiot after that did not feel abstract in the slightest.

This week’s reflection is about two things that become much harder to ignore when life slows you down enough:

your body
and your voice

The two kavanot I’m focusing on this week are:

Tazria: Respect the rhythms of body and life
Metzora: Speak truthfully and repair quickly

Watch the video, then let me know: what has a recent pause made clearer for you?

Chag Pesach Sameach.

There’s something powerful about the fact that Jews all over the world are sitting down tonight to tell the same story - in different homes, with different voices, but with a shared sense of memory and belonging.

Pesach isn’t just about where we came from.
It’s about what we carry forward.

Wishing everyone a meaningful Seder, good questions around the table, and a sense of connection - to the story, to each other, and to the bigger picture we’re part of.

There’s a tendency in both leadership and personal growth work to focus on breakthrough moments.

This week’s reflection is a reminder that most meaningful change is far less dramatic - and far more consistent.

It’s about what gets repeated.

Shabbat Shalom 💙🤍

We often assume that if we just explain antisemitism more clearly, people will recognise it.

Sometimes that’s true.

Often, it isn’t.

Because the issue isn’t just a lack of information - it’s that people are interpreting what they’re seeing through very different frameworks.

That creates a gap that can’t always be solved with better messaging alone.

I’ve been thinking a lot about that gap, and what it means for how we respond.

I wrote something longer as a follow up to my video exploring these ideas from earlier in the week.
