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
