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.)
