All: Unthoughtful comments should be downvoted. Have at it.
Edit: I've mollified my wording slightly. Please downvote judiciously.
I was talking about the invitation to pitch in how to solve the general problem of hateful comments. Which I think shouldn't be discussed here, because it's not only a problem of this specific submission.
Sorry if I misunderstood this invitation.
We're going to solve this problem sooner or later, because so many of us are sick of it. But the specific form the solution takes has to evolve in the community. When systems are evolving, overspecification is a mistake. For that reason, I'm going to stick to commenting on particular examples for a while.
