"So I guess all you people who resent the modification (on the grounds it wasn't considered wrong at the time) would also welcome repeats of Jim'll Fix It. "
Slightly different issue, but it wouldn't bother me in the slightest as I've no wish to airbrush history.
I say it's different for two reasons:
Firstly "Jim'll Fix It" was not a historic portrayal of history. It was a series made by a person who has subsequently been discredited.
However, more importantly, the alleged behaviour by Savile (assuming the allegations could be substantiated because they've never been properly tested) would be as unacceptable then as it is now. It's not the same with Guy Gibson's dog. In the 1940s nobody would have blinked at a dog with that name. You might as well say that stories portraying Anne Boleyn being beheaded, or women not being allowed to vote, or domestic violence being acceptable, or people being hanged for murder should be similarly censored.
