My lecture on the History of Antisemitism, censored by YouTube, is now back online. Here’s the takeaways.

Join me at 12 noon (ET) for a live chat on this topic.

Here’s the link to the controversial video (my part starts around 41:00).

Sectarian Infighting and the Fall of Jerusalem: Tisha B’Av lecture for Sunday

Sunday: YouTube 1pm ET, live at Young Israel of Lawrence-Cedarhurst at 7pm ET

Good morning fellow students of Jewish history. In a few hours we will begin Shabbat Hazon, marking the last transition to Tisha B’Av, the most tragic day in the Jewish calendar.

As in previous years, I hope to lecture on the history of the Roman-Jewish war that resulted in the destruction of the Temple. This year–influenced in part by personal experiences–I’ve decided to focus on the topic of Sectarian Infighting and the Fall of Jerusalem. Please join me at 7pm on Sunday for a live presentation at the Young Israel of Lawrence-Cedarhurst. For those of you who are unable to make that time and place, please join me for a YouTube premiere of this lecture at 1pm ET, which was previously recorded with a small number of Colleagues (the video will be available at 1pm).

Available Sunday at 1pm ET

This year we continue to commemorate Tisha B’Av–may we one day merit to celebrate it together in a peaceful Jerusalem.

Wishing you all a Shabbat Shalom,


Regarding my recently censored video on the history of antisemitism

I wasn’t surprised that YouTube censored my recent video as “Hate Speech.” It’s happened before.

Talking about antisemitism, violence, and even the Holocaust is part of my work as a historian, and the algorithms are obviously set to look for key words and images related to these noxious topic. So my lectures have been flagged before. This time, however, was a little different: I lost my appeal to have the video reinstated, which seems rather silly: I’m a tenured full Professor speaking about antisemitism, not speaking antisemitically, and I’m surprised that they didn’t catch the difference. But that’s okay.

On the whole I appreciate the efforts of the YouTube Creator Team, as they have made it much easier to remove the intellectual vandalism that frequently sullies the comment boxes, not to mention the mental pollution that some people spew onto the web. I’ve noticed that the filters have gotten stricter in recent months, and in general I have been very pleased with these changes.

If YouTube flags my videos by accident, I’m fine with that (at least for now). The nasty stuff is just so awful that I would rather they err on the side of caution. I can always post my lectures here, on my personal website.

I hope you find this lecture on the history of antisemitism worthwhile.

Banning critical race theory will gut the teaching of Jewish history

No responsible teacher wants to teach students to “hate each other” or “hate America.” But we all participate in a sacred covenant with our students: They expect us to tell them the truth.

Thirty-Six righteous Students now studying the history of Ashkenaz!

Hello students of Jewish history! I am very pleased to let you know that we now have a very auspicious number of students in this new experimental online course, A Thousand Years of Ashkenaz. I know some of them from earlier interactions on YouTube and in selected classes, and it promises to be a lively group, representing at least five countries and a wide range of backgrounds and perspectives.

I’m very enthusiastic about this new initiative, and I’d like to encourage more students to join this select circle. YouTube is great, but with 5,000 people watching every day (we are up to nearly 45,000 subscribers), I can’t possibly keep up with the discussions. This online class will allow us to have a more compact, focused learning environment, featuring more meaningful online discussions and feedback.

Please join us! You will be welcomed.
