Jews do have linguistic, religious and historical links to ancient Israelites. Granted the genetic record suggests admixture but as I said that’s true of everyone. You are just trying to mud sling without concern if what you say is true.
By taking extreme positions like you do you unwittingly undermine the Palestinians cause. Hardliners in Likud will just point to fanatics that sound like you in Hamas to morally justify expelling Palestinians from the region. You don’t have the weapons to compete with Israel. And no one what can compete will come to your aid since they fear the US. The only option open to Palestinians is acceptance of Israel’s existence and peaceful negotiation. Anything else will just result in Palestinians continuing to be ejected from the region.
