Thanks for your clarification, but I don't fully understand it. By your claimed criterion, most of the displacements I mentioned were "VOLUNTARY". In fact, the least persecuted of the displaced groups were the Muslims in modern India and Israel, as evidenced by the millions who voluntarily remain. So how many of the people I categorized as "displaced" would you identify as "forced" (Palestinians in particular) and where did you obtain your evidence? Personally I tried to distinguish between "evicted", "fleeing in panic", and "retreating to return as re-conquerors" but quickly gave up -- too little data, too few clear distinctions. too many biased recollecionts, tooo much fog of war.
