Without going into the validity of the source you posted above it does not appear in the aritcle does it The article only uses Tom Segev a RS about what Tom Segev thinks maybe Badil an advocacy group and Internal Displacement Monitoring Center which uses Badil as a source This article does not quote the definition used by organizations that specialize in dealing with internal displaced persons like you re trying to imply it assumes something based on one advocacy group counting decendants It is certainly not OR for me to question the validity of the sources or conclusions of an article and what you call my theory was just an appeal to common sense
