He seems very sincere.
Alan Dershowitz may be a Dem, but he is most assuredly NOT a “Jew-in-name-only”.
He has not subsumed his religious and ethnic identity to the false god of cultural marxist progressivism.
And what Alan Dershowitz has witnessed in recent decades (as we all have), and what he has strongly criticized, is the rampant growth of anti-semitism across the Western world - nearly all of it coming from the LEFT.
Since the enemy of my enemy is my friend, he has therefore moved closer to our side.
Speaking as someone who lost relatives to the Nazi occupation of Europe, and whose father fought them behind enemy lines for 3 years, I welcome Prof. Dershowitz to “our side” in this battle of civilizations. The left has lost its mind all across the world.
The only nations on earth where the books “Mein Kampf” and “The Protocols of the Elders of Zion” are taught to children as factual history instead of as the vile anti-semitic fantasy and Czarist-era forgery that they are - are the Mohamedan nations - which the Western left has embraced (!)
That is not lost on anyone with a trace of a soul, or with a trace of a sense of right and wrong.
