Some Jews are so deeply enmeshed in a delusional world of murderous anti-Semitic non-Jews that rational interfaith discussion becomes impossible, and for such Jews anyone not sharing the delusion is an enemy. At least Rabbi Seltzer makes it clear where he stands. It is much more difficult to deal with Jews that hide their delusional mindset.

I have a collection of Harris' articles and essays. He clearly belongs to the latter group of Jews. Debating such people — either in discussion of interfaith or Zionism — is usually fruitless.
