>>>I'll sign off after this, as it's not clear to me whether I'm being effective.

I hope not, I believe this is a decent conversation. I understand your point, and yes some of my comments are flippant and oneliners, I personally believe those kind of comments are relevant and constructive as well. hell the last election was won with bumper Sticker rhetoric. Not everything needs to be a dissertation

I seems to me that I am the one being ineffective, as it seem you have come to the impression that I understand my comments would be downvoted and/or that I know my comment is "nonconstructive" and have chosen to post them anyway. This is not true, my original comment that started this was a parody of the comment I replied to, i did not add more because the original comment did not have any additional substance. They made a statement of fact backed by no data, and I made a statement of fact backed by no data. The political bias of HN lead to my comment, which IMO has clear historical reasons for being true prediction, Was downvoted multiple times whereas the parent comment gets up voted. [My comment as since rebounded and is now in the Positive, it was in a negative when this conversation started]

Your claim however is the downvotes are not motivated by politics or disagreement but instead because the community believes it was a unconstrictive comment. this is the basis of our disagreement and resulting conversation.

>>>Member begins commenting in a way that's unconstructive.

That is a big assumption, that downvotes == unconstrctive. when more often downvotes == unpopular or against the mainstream view.

Contrary to every web sites attempts and goal down votes are used by users to express disagreement. So if a person disagrees with a post regardless of it substantive value to the conversation it they will down vote it. So to assume a heavily down voted comment is unconstructive is a terrible, and flawed assumption to make

Also I Pretty sure on HN rate limiting is an automated not manual process. If I am wrong on that then may opinion would shift to the moderators which I will not comment on as that seems to be instant ban here...

>>>You acknowledge the rationality behind rate limiting, and feel frustrated when it's applied to you

I understand the logic they applied when creating it. To limit spam, flame wars, etc. I do not agree with that logic and believe it a failed and overly aggressive policy. If anything it should be thread not user based, meaning the thread should be rate limited instead of the user...

>>>Continuing to comment in ways you're aware are against the guidelines or you believe the mods are going to react poorly to is very likely going to get you banned eventually, with frustration all around.

Well technically speaking any comment is "against the guidelines" if is deemed so by the moderators, HN guidelines like most sites are written is such an overly broad manner as to include anything and nothing at the same time, all dependent upon the mods subjective opinion and personal bias. This is not just a problem on HN but every websites anymore as the political landscape gets more polarized and people start creating echo chambers for themselves, and HN is a political echo chamber even if it attempts to claim an apolitical stance.

>>>I think your options are to limit your discussions to non-contentious topics, or to stop commenting all together.

Where politics meets technology is where my interest lies. No topic I am interested in non-contentious. I desire to advocate using technology to advance individual freedom, and guard against using technology to create or aid Authoritarian societies filled with surveillance, censorship, and tyranny. As the technology industry in general along with HN moves more and more away from Individualism and more towards Authoritarianism my views seem to considered "destructive" even though 5 or 10 years ago they would not have been. I desire to see HN and society in general shift away from this Authoritarian censorship culture and more towards Individualism and free speech. I simply can not self censor to the point where I only comment on apolitical topics as that will only allow the echo chamber to fester.
