To be clear: what he's saying in this thread seems to support the idea of a karma-limited feature for showing comments. The score (not the content) on a comment would have been negative; the comment, in context, was a superficial negative comment that commanded the top spot on a thread.
At the very least, the intuition seems to me that if you have a high enough karma score, you've learned by example what is an acceptable and unacceptable comment and know how to compose comments that are acceptable, and should be able to tell the difference. Beyond that, if you set the knob high enough, you're going to capture people who have been around for a while and have been able to witness the rise of the pendants and armchair-experts compared to yesteryear so won't dismiss these things as "normal."
