On Whether the People from Syria and Egypt Who Bum-Rushed In to Palestine During the Turkish and British Empires Should Ultimately Be Seen as "Settler Colonialists"

Depends. If you're making your assessment based on moral consistency, then of course they should be (and please don't give me any bullshit about these people coming from the region and so therefore they couldn't have been colonial types in that half of Israel's original Jewish population also came from North Africa and the Middle East). However if you're looking at it strictly through the prism of perpetual Jewish hatred then, no, they shouldn't be. Simple as that.
