Why do they want to be with us if they treat us so poorly?
they don't "want to be with us" in the same manner of thinking as YOU possess........they see a super handy target to take out all their angst upon.....someone they can belittle and berate WHO LETS THEM....they are rulers of a very small fiefdom.....and if they let the serfs LEAVE, then that indicates they are no longer powerful and strong and in control.....shine the light too close and you start to see chinks in the armor.
and often because they are just jackwads.............
