I'm not comfortable with that. It's hard to put my finger on, but it misses something critical. It is somehow wrapped up in the idea that for such absolute avoidance to be the rule, we'd have to be reinforcing the need via deliberate, organized action, not the incidental act of a few bozos taking pot shots. Anything that big, that organized, we'd know we were doing it. We don't. So .. we aren't. I have to conclude the answer lies elsewhere. Not sure where, but not there.
