Of course you can - plenty of HN commenters make such critiques. But you need to do it without swipes, snark, name-calling, or flamebait, as the site guidelines ask: https://news.ycombinator.com/newsguidelines.html.

Every sentence in your GP comment was flamebait—exactly the kind of thing we're trying to avoid here. And yes, if you start a flamewar comment a la "It's so damn $country", that's nationalistic flamewar in the sense that we use the term, regardless of which nation you have a problem with.

This kind of thing ends up producing internet discussion that is equal parts inflamed, predictable, and dumb. We want curious conversation here.
