what have you got against tents? we used the same argument to steal land from the boongs and the injuns. just because they lived in tents doesn't mean they didn't live there.
There is much more going on here than just a dispute of sovereignty between Israel and wanna-be Palestine. The root of the issue is not politics. That certainly plays a role and colors the entire conflict. But recognize that this is also very much a conflict of urbanization vs.a traditional rural lifestyle.
In traditional rural lifestyles, if your family gets bigger -- you just use your resources to farm or graze more land. Surrounding land is abundant and "free" for use. There is no discussion of "ownership". You just make your farmland a little bigger. If your family grows -- you just build a new house to accommodate the son and daughter-in-law and their children.
There is an essential conflict between that way of life and an urbanized way of thinking. Where land must be purchased, and building permits obtained and urban plans adhered to.
