I didn't say they shouldn't move on. I don't know if you read what led up to that, but basically, somebody made a cavalier, "I don't care who I offend, we should do it!" comment. The point is, there's a difference between things like this, where it's pure coincidence combined with overreaction, and, say, somebody directly and thoughtlessly joking about it or shoving it in their face.
Like I said, this would be horrible if it was intentional, but I sincerely doubt it is, and in that case it should simply be ignored.
