I think it's a moot point to be honest- gay people have always existed and always will, they did the same things in ancient Rome with one another that they did in 1960's Liverpool and still do now all over the world. How or why is that shocking? Elderly people are no more fragile than younger people, in fact you will have as many elderly gay people as you will have young gay people, so why the problem or embarrassment? If people cannot accept a representation of events relevant to a story they are watching unfold, they might want to consider selling their TV, as I don't think the rest of us would be too happy with their sanitised productions.
