They don't even know enough to be ashamed. They don't even know what shame is. They don't even know they don't know which is worse than not knowing anything at all.
Somehow, between the time I was born and today, the people around me just slipped away and were replaced by critters that don't quite stack up. They're humans-lite, like those white brand products you see at the supermarket. They cannot produce enough points to qualify for a rating as humans. They're just shambling bipeds that drink beer and watch football and shop. If you speak to them, they give away within a few sentences everything about themselves and they don't know they give it away. They're not even bright enough to imagine anything better or to visualize a past or a future that is different.
I have to say, the frequent assertion by beany babies that they are biped cattle has a lot to recommend it. I can't help but think that is a very accurate appraisal.
