I don't listen to The Archers any more, but I welcome the idea of a black character who's story line could easily be about a white character. As I've said before, the problem with too many British dramas (up until relatively recently) is that whenever writers introduce a black character, their defining feature is their ethnicity, with the resultant storylines evolving from that.
What the producers of The Archers should be congratulated for, is introducing a character with a juicy storyline which is not about them leaving the city to avoid drug and gang culture; for not making the character a DJ; and for not 'playing up' his ethnicity.
Incidentally - this has all happened before with the Scottish character, Jazzer. He's still on the show (at least he was when I was last listening to it):

After a while those whose jobs it is to get 'professionally outraged' soon move on to new stories.
