Ah yes, the ubiquitous middlebrow dismissal (https://news.ycombinator.com/item?id=4693920 http://www.byrnehobart.com/blog/why-are-middlebrow-dismissal...). "As a non-kernal guy" gives it away immediately.
The parent comment is not so much a put-down as much as it calls out a particularly unsophisticated dismissal. The parent-most comment would have elicited the same useful information if it were phrased as a question, but would have been less uncouth. I think that's a perfectly fine thing to write a comment about.
