You've entirely ignored the thrust of the parents argument.

I'd also point out that from the perspective of a secular westerner, even if one group is calling for the genocide of the other regularly; is the other group, which is actually committing genocide regularly, able to be held up as morally superior in any way? Is that group (Israeli Zionists) actually worth defending at all?

You have to remember that for the vast majority of the world, neither religious viewpoint holds much weight; only the globally agreed common ethics.
