Erasing thousands of years of indigenous history, especially when it’s not at all necessary in order to support the human and civil rights of Palestinians or the integrity of their collective narrative, is not antifascist or decolonial.
It is antisemitic, both in what it says (that Jewish history is at worst literally nonexistent and at best an inferior historical artifact forever subordinate to the colonizer’s political and cultural claims) and in what it implies (that Jewish people are thieving liars not worthy of the basic human right to self-determination in all senses of the word).
