I can definitely understand that as well. I rely on someone replying to the comment if I say something that is unclear or misinterpreted. It allows me to have better feedback anyway then trying to figure out where I went wrong on my own, plus it avoids being able to dismiss it as “well maybe it was just a unpopular opinion so it was downvoted”. I also find effort a huge factor as well, meaning that if someone went through the hassle/effort of responding to my comment then chances are it’s not an opinion type deal and more of either I wasn’t clear or there was a misunderstanding. (when the reply is opposing of course)
