“erasure of the actual descendants of ancient Hebrews… the Palestinians…”
It seems to be true that Palestinians are partially of ancient Canaanite heritage… including ancient Hebrews. This does NOT make you Jewish though. Having a little DNA due to mixing with Jews over the ages does not make you Jewish. If anything your aversion to Hebrew culture making you antisemitic.
Using your having a little DNA in common with xyz as a rational for one’s identity…. anyone can claim to be anything. Russians become the “real” Chinese. Slavs become the “real” Greeks. .Poles become the real Germans, George Bush becomes the “Real” native indians. Turks become the “real” Arabs. And so on. The cultural choices we make and history inbetween past and present also play a role in accurately defining what a person is not just a few strands of DNA. You are making the same mistake Nazis made of confusing their pseudo-scientistic blood theories of themselves as racially pure Aryans with reality.
