It's not whether they are a nation separate from other Arabs, it';s whether they are a group separate from other Arabs. In other words, those Arabs not covered by the term "Palestinians". since that is a valid term. I assume you accept that? Kind of like how if something can be described by the word "broccoli," it can't also be described by the word "rhinoceros." Or if some thing can be described by the word "word," it can't also be described by the word "someplace". or how if a thing is a thing, it really is that thing, and not another thing. Or kind how the letter "T" is not also the letter "W". -) does that make sense? thanks.
