The man is SO on !
I have a very liberal cousin who has a terrible time getting along with her sister. They live half the US away from each other, spending actual time together for maybe a week or so out of the year. They have no weighty issues between them- it isn't as though one of them slept with the other's husband or anything-just childhood resentments.
And yet this cousin cannot conceive of a world where two people have such different points of view that issues simply CANNOT be resolved peacefully.
It baffles me.
