I hear you, believe me. However, would you have been okay being a displaced Arab; told that you had to leave your property for the good of someone else? I think that I would have some heartburn with that even though you might not if you were in the same situation.

The vast majority of Arabs in 1948 Palestine were not-natives and rented property. They gladly heeded the calls of Arab armies to leave to allow for these armies to more easily make the Mediterranian incarnidine with the remains of Jews.
Arab ownership of land is quite rare. At best, many lease it from other landlords or from the state.
The real change was with property administered by the state. However, even today, more private land in Israel is held by Arabs than by Jews.
PS. Ethnic cleansing after WWII has helped prevent wars.
I don't see you crying over Jews who lost land in 1929, 1948 or today.
