Three dimension
My way,Your way, Compromise
Two dimension
My Way or the Highway
You see clearly that one dimension is missing and it is not their fault. They did not ask to be born missing a dimension. So whose fault is it? I dunno but I do know they would be far happier creating a world that is as two dimensional as they are somewhere out there and then move there. AND STAY THERE. And the three-dimension folks would be very happy to have them go there and stay there as well.
Everybody wins. How can that be a bad thing?
