It's amazing the level of patience you have for the insanity that is DNA construction, but zero for idiot comments. I guess it's all used up on DNA.
I think you need to define your terms.
Okay, it's not ZERO. But significantly less.
I think the relative incentives play a factor.
Enduring the Kafka-esque (I feel a new term for this is required, but I can't think of a better one at the moment) madness that is DNA construction leads to continued DNA operation, which is something jwz clearly values. Not going through all of this would, y'know, stymie his efforts.
Enduring idiot comments gains him nothing, and not enduring them costs him nothing save a banhammer click or two.
Sadly, he probably means "DNA construction" as in "bourgeios changes to DNA Lounge", not as in "the brilliant unspeakable tentacle horrors you inflict uponhumanity that burn the mind and rend the soul".
