Christians believe they are the real Jews,
Muslims believe the real Jews are Muslims.
That’s why some call these religions “Judaism for non-Jews”.
And something else:
Those who today call themselves “Palestinians”
have always thought of themselves as Arabs.
In modern times claims have come up that they descended
from Canaanites, to establish prior claims to the land,
from Philistines, to establish themselves as the *real* Palestinians,
from Jews, to arrogate to themselves blessings
which are said to have been bestowed upon Jews.
John, this is politics, not genealogy or history.
