“Palestinianism?”
Yup Palestinianism. Your claim you are the only indigenous people to the region is a fiction of your vivid imagination. The “ethnic” Palestinian identity is the result of sundry Arabs that lived in the region constructing an “ethnic’ Palestinian identity over the course of the 20th century. Like everyone else, you are of mixed heritage champ. Sorry to interrupt your crypto-nazi fantasies of yourself as racially pure descendents of ancient peoples that lived in the region.
