OK, so you're from Canada. ... Have you ever been to the Middle East?
I am Canadian and living in Canada. Of course I have been to the ME. And not 50 years ago.
I think you have the conflict reversed.
Pretty sure I haven't. Self-determination for the Jewish people (who are clearly indigenous to that land and who have clearly inhabited that land for millennia). Self-determination for a specific national group of Arabs (who have also inhabited that land for some centuries).
There is no conflict with this stance. The conflict only appears when self-determination is demanded for some and denied for others.
How do you deny the simple fact that Palestinians were there first and that modern day Israelis are no more related to the Ancient Hebrew warriors than they are related to the Eskimos?
How do I deny it? Because it is a silly stance to take. The collective of the Jewish people is an ethnic designation incorporating culture, language, religion, history, life celebrations, holidays, rituals, and all the things that make a distinct people a distinct people. There is NO QUESTION that the Jewish people are the only existing people whose ethnic culture originated in that land and lived on that land throughout their history, despite the forced diaspora. And there is NO QUESTION that those who continued to experience and pass on those cultural practices belong to the collective that is the Jewish people. (Last I checked, Inuit do not speak Hebrew, nor do they follow Jewish custom and law).
On the other hand, the collective of the "Palestinian" people is a national designation, not an ethnic one. There is no collective which holds and carries a unique and distinct culture which can be identified as "Palestinian", as distinct from Arab or Muslim. Arab Palestinians hold a culture of colonization and conquest. Arabic is not a native language to that land. Islam is not a native religion to that land. The culture and customs do not originate on that land.
Declaring that "Palestinians" were there "first" makes "Palestinian" a nonsense word. It entirely dismantles any distinct definition of "Palestinian".
And NONE OF THIS MATTERS. Because it doesn't matter what conditions create a distinct group with inherent rights to self-determination. If we subscribe to the concept of self-determination, then ALL groups hold that right.
