I know that there are varying opinions on comment dismissals. Some people think it's rude except in cases of extreme trolling. Some people never do it. My thought is that it's my thread and you better be nice. Straight up. You like your opinion so much, start your own thread. Also, I tend to view GM commenters like sharks: they get truculent at the scent of blood in the water. One shit comment leads to twenty because we've created a culture wherein bitter arguments and preaching win the day. There's no room for principled disagreements.
My question is this. Have you ever explained to someone why you dismissed their comment? My thought on the matter is that it would lead to more arguments.
Curious to hear your thoughts.
