Here's one of them. I could spit through dozens of comments and put a whole list of comments here to satisfy your request further - but would it make a difference? It's well known (and probably verified research can confirm) that vote-systems adhere to common denominator circle-jerking.
There's "out of the echo chamber", and then there's "fully out of the scope of HN", and debating the merits of Turkey's suppression of the Internet vis a vis the Internet as a conduit for western propaganda is "fully out of the scope of HN".
There are good places to have that debate, and HN just isn't one of them.
That comment was (a) not substantive, and (b) inflammatory. It was appropriate to downvote it. I'd guess it got more downvotes for being a (very) minority view than it otherwise would have, but that doesn't mean it didn't deserve them.
By "not substantive" I do not mean false, but rather that the signal-to-noise ratio of a comment containing many grand, unsupported claims is low.
Since you don't want to provide us with dozens of examples, how about picking, say, three that have the highest signal-noise ratio of the lot, and weren't uncivil? I'd like to see those. I know such comments exist, because I see them, yet the people charging HN with groupthink never seem to cite any clear examples.
