So tell people not to yell! That's the problem, not discussing a topic. Plus the biggest yeller got banned so I don't think it'll be as much of an issue.
I get that some people are bored of them, but they're going to be discussed and then Blizzard is going to announce the expansion and there'll be no mention of subraces whatsoever and basically we're all going to die of shock. Like, the floor will be covered in spilled cups of tea and monocles, just everywhere.
