That’s not at all how any site with a downvote button works. They’re used to hide what you don’t want to see or what doesn’t fit your narrative. You’ll see this on HN as well if you stay around long enough.
Same holds for upvoting, many times I upvoted posts I did not agree with but that raised interesting observations on the topic discussed.
This is what makes HN great in my opinion.
