There is a certain brand of conservative Republicans who have learned to weaponize antisemitism against Democrats. The general operating theory is that, since the Holocaust, anyone with even Jewish heritage can do no wrong (though I question the sincerity of the view).

Palantir's CEO, Alex Karp, is the son of a Jewish man. I specifically say "son of," because I understand Jewish heritage to be matrilineal and I don't see Alex Karp engaging in any specifically Jewish traditions. But he does also seem to be one of the "Weaponize the Holocaust" Republicans. Thus, you get defenders such as this.
