Broadly speaking, religion is not diminished by scientific discovery, it is diminished by people’s material needs being met and their prospects looking good. Our friend Marx called that one a long time ago, but modern studies on secularization say the same thing.

But Israel/Palestine is not about religion except as a smokescreen. It is about race, specifically an overwhelmingly white population of settler colonists creating and expanding an ethnostate. The aggrievement of the Palestinians is not that Jews exist, but that their homes were taken and their family members and friends were butchered like animals.
