There are a number of continuously running threads on the Points of View board all making exactly that point. Occasionally the BBC puts up a spokesperson who says something like, "We've done focus groups who aren't offended by these things so yah-boo!"

In this case, however, the host on the messageboards promised to personally find out who was responsible and yell at them on Monday morning. I believe Mr Moffat was also furious and likely to be on the phone too.
