Rabbi Shmuely Boteach has recent written an article about the seder at the Obama White House, and in the process weaved in some of the current US-Israeli politics. It was very critical of Obama, to the point of attacking the President's character. Not something I would approve of in any circumstance, and not surprisingly it provoked a lot of outrage from the Huffington Posters who read it (which were not very many). Some of them crossed the line to make both anti-Semitic and abusive comments, including personal attacks on Rabbi Boteach.
