Personally, I find "Question Everything" the only dogma worth howling along to.
Forums like this tend to produce "Accepted" solutions that are argued blindly for. I certainly mean dogma.
I'm surprised at some of the headlines that make it to the popular page. Not sure what to do about this. Maybe it can't be completely automated. Maybe there has to be some amount of manual curating of stories.
Mods have the power to weight stories so that they stay on the first page, second page, or drop off completely. Points don't matter if a mod likes or dislikes a story. Think of them as Editors and we are submitting stories they (the mods) may enjoy. The point value on the story is irrelevant.
A single person with 500 karma can "gray out" your post and suddenly you're outed as someone with a "wrong" opinion.
Users have the ability to flag posts, essentially make them invisible if they don't agree with an opinion. Get a few users to gang up on someone and you can silence people and ideas easily.
Points on HN are an illusion. People with 500+ karma and the mods are the only ones with power here.
For example, moderators don't count for more than voters on HN. The site is moderated [1] but this is a sort of feedback mechanism to prevent the system from getting stuck in an uninteresting end-state (e.g. overwhelmed by the same few sensational stories over and over). The only thing we care about is keeping HN interesting for the community, and it's the community that decides what is interesting, not us.
The bit about users with 500+ karma is also wrong, but I doubt it makes sense to bother going further into explanations.
