As a comment gets more likes vs dislikes, it rises in the list, correct?
Just like too many dislikes vs likes and it goes down and potentially get's hidden?
Why not have the list always be made top down by first come first serve?
Not only does that force people to read through more than just the top few to get a proper feel, but it's easy enough to see the likes vs dislikes.
That way you can leave both like and dislike alone, and refrain from hiding.
I don't see the point in overly propping something up or hiding it, other than maybe to reduce a really long string of comments here and there.
There's a "Sort By" option at the top of the article section. You can have it in newest/oldest order, or even the downvoted comments at the top if you want.
As for the topic, if you don't want to get downvoted then don't say stupid things. Simple.
