The Daily Mail's article about the Archers should be treated with kid gloves, because again, it's cobblers.
90 complaints?
With an audience the size that The Archers has - 90 complaints is statistically irrelevent. I'm not saying the views of he complainants are themselves irrelevant, but taken as a percentage of those listening, the numbers are meaningless.
I bet if you polled listeners, you could find 90 people who disagree strongly with the female character who decided to have a child using a sperm donor (can't recall her name), or 90 people who were angered by the way that wayward teenager (who had dated one of her college lecturers) was portrayed.
This however, won't get people worked up.
What The Daily Mail has sneakily done, is focus on a trivial number of complaints, and then broadcast it on their site as another example of people 'crying racism'.
Remember...90 people.
