My observation of today is that the large scale, society based horrible things that happen are not the fault of the fringe extreme. Yes, the wackanuts are the ones coming up with the bad stuff and driving it forward. But these are usually a minority. The problem comes about when the so called moderates let the nutters advance. Either by tepid opposition or by tacit approval, either way, the vaster middle is the gatekeeper.
I don't much care for the unthinking moderate.
