Sounds like you're just jealous.
Because he's insecure in his own beliefs? Because he takes religion too seriously?
That depends. Did the religion start with one people and proliferate through proselytization or did it not? If you're referring to Judaism, they're definitely more than one race of Jews.
I don't have a problem with little to no diversity. We'd be in a lot better shape had the US and Europe done the same.
They have very little of it. And good on them for not falling for PC bullshit. If anything, it sounds like you're jealous that they maintain that lack of diversity, and that's okay. I am too. The difference is rather than blame Israel for defying PC BS, I blame my government for allowing it.
I don't know. You're the one talking about them. They're obviously living in your head rent free for some reason.
