1. There's a lot of irony in your statement, since Jewish people were slaughtered and horribly mistreated in those other countries simply for being Jewish. So how have they not been ethno-states... or at least "anti-specific-ethno states"?

2. There are plenty of countries that are dominated by Islam, and yet their right to exist isn't generally questioned.

Yes, they used to be. That's usually how nations are born - around common ethnicity.

And that's the point, everyone else got criticized for it except for Israel, which has a bipartisan support (at least in America). And any critique of Israel being a Jewish state is somehow portrayed as a double standard against Jews. At the same time you can freely attack white, non-Jewish people on the basis of what European and American governments did without any fear of repercussions. Not saying that there should be repercussions, because I support free speech, just pointing this out.

The first part of your comment refers to Jews as ethnicity and the second as religion.

There are several Christian and Islamic countries but only one Jewish one.

Seems like you're changing the subject to talk about religion.

Can we assume you cede the point regarding ethnicity?

What do you think "Jewish" means then? You think being "Jewish" is an equivalent adjective to being "French"?
