A sample size of one doesn't really tell you anything in this context. HN definitely has a pretty heavy bias in some directions, it's mostly that the crowd that naturally flocks here tends to mostly agree on those topics, so you don't see conflict too often.
I feel like I often get into protracted discussions here in which I am defending a minority view, but I don't feel discouraged from doing so.
A huge part of that is that the tone is almost always civil and the arguments are typically in good faith.
