The reason it doesn't make sense is that I think everyone (even his defenders) are misreading the offending sentence.

"If I were a Jew" is meant to inform his "concern" not his "appetite".

The insatiable appetite for violent self-defense is obviously universal (he mentions Palestinian animus). What is unique to Jewish identity are the lessons of the Holocaust, which he thinks would make him more afraid of allowing instincts of self-defense to overwhelm sensitivity to the suffering of others. It's perfectly consonant with his previous paragraphs.

Right-wing media isolated the sentence from context and framed it as saying Jewish people have an insatiable appetite for violence. The phrasing was ambiguous enough to plausibly support that interpretation, and people saw what they were primed to detect. Helps that he chose not to publicly defend himself, and media generally don't like to scrutinize claims of bigotry/racism. Reminds me a bit of the Shirley Sherrod firing.
