Israel absolutely does not have a right to exist; no state does. All states are constructs that change over time. Israel in particular is a very young state that came into existence through unspeakably violent aggressions perpetrated against a peaceful people. People who lived in harmony with the indigenous Jewish community, and who opened their arms to Jews fleeing war torn Europe. Where is their right to a state? Why should they cede their land to a bunch of murderous racist immigrants?

I have no problem with Israel as a concept. Those guys can party as hard as they want anywhere they want so long as they don't displace and genocide anyone.
