This feels like a confected scenario to allow you to feel a sense of grievance or do you have examples of ‘people who claim to be offended by Benny Hill's type of comedy [but who]are apparently OK with the fact that a lot of current "comedians" are unable to put a joke together without including the "F" word’?
If you are correct, doesn't your point merely illustrate that people hold differing tastes when it comes to TV comedy?
In my view, the UK viewing audience simply lost the taste for Benny Hill - presumably because there are only so many times that you can watch a man chasing lingerie clad women round a park at double speed with a saxophone soundtrack and find it amusing.
