Ok, totally true but faith and race are conflated for jews, much more so than muslims or christians. Mizrahi jews aren't called Arab jews, judaism is not a proselitizing religion in general for 5,000 years so of course it has bloodlines rather than converts.
Israel is an ethnostate apartheid system on that conflated definition. After all, religion is almost as hereditary as race.
I guess I don't see the distinction as all that important? Aside from the fact that it would be an all-time troll if 2 million people in Gaza declared that they're Jewish now and applied for aliyah.
