The natives lost something, to be sure, but I'm not sure it was property. Property is created when you kick everyone else out. I assume that's the rationale behind "property is theft," it used to be everybody's and now it's yours.
You're correct. They didn't lose property as they had no legal concept of ownership. Instead they lost their homes, their culture, and their lives. How lucky for them!
The level of respect is per treaty, a blanket statement cant be corroborated as many are not respected or dont have consensus amongst the affected people of being respected
You felt compelled to parade your ignorance by inserting this cheap shot about "Palestinians" into an unrelated discussion. What I mean by ignorance is joining the uninformed masses bleating about "genocide" and "colonialists". Presumably imagining that Jewish people arrived in Palestine de novo at some point in the 19th or 20th century and conquered the native Arab "Palestinians" there.
