The significant words there are "I’ve never seen". People see what they're primed to see. On the internet, that means you notice what you dislike. (I don't mean you personally—I mean all of us.) All the cases that go the other way are escaping your notice, or getting discounted (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). When you weight one side at approximately 100 and the opposing side at approximately 0, things feel appallingly unbalanced. Everyone with strong passions, on any side of any $topic, is doing a version of that and therefore feels that way.

Because this mechanism is so reliable, I can tell you for sure, even though I have no memory of what your ideological preference is, that the opposite side is every bit as convinced that we're biased in your favor against them, and every bit as "Gee-I-wonder-why-that-is" sarcastic about it. See https://news.ycombinator.com/item?id=26148870 for a panoply of examples; there are hundreds more where those came from.

Re the other comment you mention: I'd need to see a specific link to be sure which other comment you're talking about. It's possible that I just didn't see it (we don't come close to seeing everything), but it's also possible that the other account isn't using HN primarily for ideological battle. That word primarily (which you'll notice I used in my reply to you) is critical because it demarcates one line at which we ban accounts. Past explanations of that point: https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme....
