They're really not. What's true are the experiences that led you to feel the way you do and the fact that you feel that way. But retrofitting that into a social theory with a grab-bag of data points doesn't yield truth. It's just a form of intellectual armor so you can make aggressive claims without being vulnerable where it hurts.
If you gear up with that armor and then charge into HN threads and throw your weight around, that's not dialog, that's battle. It'll get angry disagreement from those who don't align with you and angry agreement from those who do, but what we won't get is thoughtful discussion. That's a problem for two reasons: (1) it's predictable and therefore boring—the true sin on HN; (2) it produces more of itself and destroys everything else. Flames are a good metaphor for this, so the term flame+war is about perfect for it.
