I'm sorry some of you feel so affronted, the program was made (as it seemed to me) purely to give the women something to do while their OH's were deployed, they enjoyed it & so it grew. No inferiority suggested, or felt.
There were GF's in the choir, but the WAGS label being attributed latterly to brainless bimbos who marry/live with footballers, they went for the Military Wives. (one lady had a DH AND a DS overseas)
It happened to be that no male OH were available or wanted to join,perhaps.
There were choir members from 2 main bases, Chivenor & Plymouth (which is far bigger) and far from gloss over the many losses, there was a frequent refrain that they were aware not all the men were coming back, that they all dreaded THAT visit & their thoughts were with the women who had suffered losses.
The whole point if then going on to do a single was to help the 2 big charities that support these very families, Gareth Malone has a grandfather who has been greatly helped by the RBL so he felt this a way of giving something back.
If anyone is uncomfortable with the term "Military Wives" then that is your problem, please don't infer these lovely ladies are anything less than independant strong women in their own right to choose to support their OH's.
I'm a feminist but I do think you can overthink things.
