Race is a social construct. That doesn’t mean it isn’t real. The constructs of “Israeli” and “Palestinian” are as real and deadly as the geographical boundaries they each draw.

If one’s ancestors define legitimate claims to where one can live, then one cannot legitimately live where one’s ancestors were not. In a weird way, the historical returners do a full swing to the xenophobic anti-immigrant types. (There are people who I’ve heard seriously argue that accepting Palestinian refugees is literally genocide.)
