“Israeli settlers should return to the country that they or their family came from originally.”
Oh? How far back are we going here? What if their family originally came from Palestine? What happens then?
“This is not like settlers in the America’s where we are talking 200+ years of families living there.” This is an interesting point that is literally under contention right now because those people came from somewhere and we don’t even know who was here first because it changes every few years. How many years of settling constitute the land belonging to you?
Where did the Israeli people actually first come from. Go back far enough and crazily enough I think you’ll find that these people do have historical roots in this locality before WW2. This conflict spans probably close to a thousand years. Picking and choosing which bit of history supports your narrative doesn’t invalidate the rest of it.
