My karma score is approaching 8000, and I promise it's enough to downvote other people.
I dare say there is some groupthink on HN. There is groupthink everywhere where like-minded people congregate. But I've seen a very wide range of ideas treated with respect here, and pretty much the same very wide range of ideas treated with contempt, depending on who happens to be reading and responding.
If you are a new user and you actually want to communicate with people...and hold a minority opinion...you will be downvoted out of visibility.
I was a new user. I hold many minority opinions (including ones diametrically opposed to those you have named as critical points of HN consensus, particularly on the issue of political ideology), and have expressed them from very early in my time on HN. I haven't been downvoted out of visibility.
I suspect that you are both misattributing the cause of the karma hit your earlier account took and falsely generalizing from that misattribution.
It's perfectly obvious that holding a minority opinion can't guarantee getting downvoted into oblivion, for the boring reason that you can hold that opinion without expressing it, and in that case no one can possibly downvote you for it.
Of course you might (very reasonably) not want to censor yourself to that extent. Very well: all you need do is have some other things you can talk interesting about besides your shortlist of pet dislikes. Then the upvotes you get from being interesting on other topics will outweigh the downvotes you allegedly get from daring not to be a libertarian. Although, I repeat: I'm not a libertarian, I've dared to express not-libertarian views more than once, and I don't recall ever getting wiped out by downvotes as a result. I've seen plenty of other not-libertarian comments that aren't invisibly light grey. So you might consider the possibility that what you got hammered for was not the mere fact of expressing an unpopular opinion, but something about how you expressed it.
Now, even the approach outlined in the previous paragraph might not be enough, if what you say about your pet dislikes gets you not merely downvoted but hellbanned. (That's the thing where your comments are invisible except to you, the moderators, and people with the "showdead" feature turned on, so you never get any karma or any replies ever again.)
But -- barring cockups and miscarriages of justice, both of which inevitably happen but are pretty rare -- that will only happen if what you say is not merely unpopular but particularly stupid, or repeatedly boring, or something else of the sort to attract the attention of a moderator and make them think "This person is not adding anything positive to HN by being there". So don't do that. Be civil. Be interesting. Don't try to turn HN into a political flamewar. It's not really that difficult.
I've been down-voted just a few times for expressing my opinion when I present a well-reasoned, logical argument. (Unfortunately I've been down-voted many times trying to be funny or posting a comment that's taken in an offensive way). I think you'll find that having a debate or even just a conversation with more than one side being taken is often the best way to see the whole subject.
I'm not saying that I want to downvote people...I'm saying that you haven't been downvoted into oblivion because you don't disagree with people.
Start commenting with a contrary opinion and you'll see what I'm talking about.
Also..."Your own biases are showing" might sounds like a reasonable and measured thing to say to someone, when you say it to yourself in your head, but its not. Somehow the rest of you have no bias?
And are you saying that I should ignore conservations that I disagree with to protect my votes...??? That's exactly what I was saying happens here. It's a self censorship that leads to this massive amount of consensus on everything from posts to comments.
I've been involved in a number of highly controversial threads, often disagreeing with the dominant view expressed in the thread, don't meet most of the standards you suggest are required to gain significant positive karma [1], and yet have over 10K karma with a current avg of 2.55.
> And are you saying that I should ignore conservations that I disagree with to protect my votes...???
I would suggest that its not disagreement with your opinions that is causing you to accumulate negative karma.
> It's a self censorship that leads to this massive amount of consensus on everything from posts to comments.
I don't see this consensus you are complaining about (and its interesting that the people complaining about supposed consensus here don't agree on what that consensus is. I suspect that's because the complaints tend to come from people that are -- likely unconsciously -- overweighting the prominence of the views that they disagree with and thus seeing a hostile consensus, and a different hostile consensus that other people see.)

And yes, your problem on your previous account was hellbanning, not downmodding per se. It is easy to get the two confused, because it's not easy to get clear info about either. Anyway, if you want to see my opinion on downmodding here, check my profile - it agrees with some of what you say about downvoting, but that is a separate issue to the stereotypes you're throwing out. The profile could probably do with updating, but it's been the same words for over two years (there used to be another section on humour, but that's loosened up a bit, so I removed it).
I loathe the downmodding system here, but it doesn't follow that this means the community is all about groupthink or the stereotypes you're promoting.
Herein lies your problem. You don't get that from disagreeing with the group or challenging the status quo; as far as I can tell, you need to have serious problems with the form, not the content of your comments to achieve that state.
I don't get many downvotes and when I do I can usually understand why.
Perhaps people expressing minority views are just doing so in sub-optimal ways?
(Having said that I tend to agree that any threads that are MS vs Google vs Apple are death.)
I think that differing views add value.
Having contrary opinions just disappear so that everyone can keep restating the same thing to each other is really frustrating.
EDIT: Clarification...
I don't think I've seen it happen on HN, but I have seen it on other sites. I hypothesize that there is actually a craving for intelligent but unusual viewpoints on HN.
How can I save this...Who wants to talk about Rust? Huh? Anybody? Bitcoin? That god damn NSA? Amirite?
I'm seriously thinking on putting some effort into collecting some examples and starting a discussion on the topic, because it's IMHO very bad tendency.
EDIT: Although in the case of your parent post downvotes are understandable.
It's usually self-correcting. A lot more people can upvote than downvote, and most people don't like seeing good comments in the gray.
It encourages group think in the extreme.
Also, at around 180 gold stars/dingles it just stops.
I mean seriously...there is a vast amount of consensus around a set of things here that are just impermeable. Yes I have read "the approach to comments" and it sounds like you guys think that "resisting decline" means everyone basically has the same opinion but everyone gets to restate it to each other in "civil" and interesting ways.
EDIT: You also have to really be into crypto-currency...it also helps if you mention hayek while talking about it. You rebel.
