I think the defense, for all the incoherence of its arguments, will ultimately prevail — not because they are right, but because it’s just too damned inconvenient to be wrong. If you think too hard about this sort of thing, you’ll recognize the injustice; recognizing the injustice, you might feel obligated to do something about it. But that means making changes in the way you live; that means giving up things you’ve grown accustomed to. It means getting off the couch. Better not to think about it. Better to just look the other way.
