Reddit's users have always struck me as fantastically antisemitic. I think a lot of them do it for shock laughs, but the genuine article is present as well.
Saying Israel shouldn't have been born in that location isn't the same thing as saying Israel shouldn't exist, but Israel is the only country whose mere existence seems to require justification. Framing Israel's political problems as if they can be easily solved by not having an Israel certainly looks analogous to solving a Jewish problem by not having Jews. I'm absolutely not saying this is what you're saying, but this is how conversations about what should have happened instead are perceived by us Jews.
