that there's a fine line between expressing dislike for my faves and outright hating on them. I'm fine with your differing opinions like "This performance could use some improvement" or "that song didn't impress me" - the most I'll do is ask you why you think that way, but I won't get too upset (or if I do, I'll get over it). Now, if you hate an artist or whatever and aren't afraid to flaunt your hatred, that just might get me angry enough to clap back (if I have a good comeback lol otherwise, I'll just report you for bullying).
Oh, and on top of that, just because you meant your mean comment as a joke, doesn't mean it is. Using the ship name "Gae" for Suga and V, for example, and claiming it to be a joke, is not it. That's not a joke, that's homophobia!
