As long as nobody's forgetting the Qibya massacre I don't really think much empathy is lost. It's a dirty war fought by ideologically-motivated pundits on both sides. The current US administration can barely even show their support for Israel without being (rightfully) questioned on the morality of supporting things like the Hannibal directive and Dahiya doctrine.

If this was just about Israel being a primarily Jewish country, there would be no discussion. It is more broadly about the IDF pushing the boundary of war in ways that makes other first-world countries uncomfortable by association.
