Those in the grip of an obsessive, irrational hatred can’t keep themselves from expressing it, even when they damage their own interests in the process. For Louis Farrakhan, recently kicked off Facebook for his bigotry, it clearly hurt him to denounce “satanic Jews” to a Catholic congregation in his latest unhinged diatribe.

For Rashida Tlaib, saying she always gets “kind of a calming feeling” when she thinks of the Holocaust, and suggesting that Palestinians created a “safe haven” for Jews in the Middle East, obviously undermined her already shaky position with her House colleagues. For Tlaib, she wasn’t even asked about the Holocaust, but brought it up in the context of her one-state opposition to any Jewish homeland, anywhere on earth.

Irrational anti-Semitic outbursts not only threaten Jewish people, but simultaneously menace the blighted obsessives who can’t stop themselves from uttering them.
