For what it’s worth, I think those comments of yours were probably downvoted “honestly”—by which I mean not that I agree with the downvoters, but that I think each comment was downvoted by someone who specifically didn’t like that comment, rather than by someone who disliked something else you’d written and wanted to punish you harder than they could by downvoting just the thing they didn’t like.
(I do have the impression—to which your examples are relevant—that left-leaning comments get downvoted by right-leaning users here more often than the other way around, even though we have rather more left-leaning than right-leaning users. I don’t trust that impression very much since it’s easy to see how it could be wrong.)
I got a −1 for posting in the same discussion here, which suggests 3). I also got a −1 for answering a question that specifically asked to explain criticism, and lost a lot of karma for [trying to defend an opinion which is popular in the outside world but is unpopular here. (I got modded down for most of that, it’s just that several of them were counterbalanced by people moderating up. The last ones did not have anyone moderating them up and left me in the negatives.)

You didn’t defend an opinion. You just stated an opinion.
