Lets say that you're sitting at home with your wife, sipping coffee and watching TV. Someone knocks on your door, you go to answer it. At your door, are 10 men armed with guns, telling you that according to their religion, their God told them in their dreams that your property and home belong to them, so you need to leave. What would you do? I'm guessing you'd have a problem with that. And if that's the case, then you can understand why the Palestinians are upset.
