I don't watch soaps and haven't heard the Archers for 12 years. But, I am aware of the stronger stories because they are often mentioned in the news. The soaps have, I gather, dealt with not only gay relationships, but fertility, cot deaths, Alzheimers, other life threatening illnesses and suicide. If just one person watching a soap gets a degree of comfort from finding out that they are not alone in this world then that is a good thing.
It's not always easy to tell if someone is gay. I remember back in the early seventies I worked for a few weeks in a dry cleaners in Kensington. Shortly after I joined the business was taken over by a gay couple. After that, lots of good looking men came into the shop and my only thoughts were that they were a loss to women kind.
