Sorry to break it to you, but editing something out of a TV show doesn't make it go away. It still happened. All we are doing with such edits is conveniently brushing things under the carpet.
To address the 'can still watch paedos' purely from what you would want to watch, there are nuances to this. From my own examples:
Until it stopped working about a year ago, I still had a VHS player. A couple of years ago I watched a film I had taped off the TV way back when. I had obviously let the tape run when recording, and when I was re-watching I decided to see out of interest what was on after the film. It turned out to be a programme that was a tribute to Jimmy Savile - people who'd been on Jim'll Fix it saying how great he was. Obviously I didn't want to watch this so I exercised the facility to which we all have access - the 'off' button.
Staying with Savile, I have the DVD box set of 'Life on Mars'. There's an episode where Savile is the person who talks to Sam Tyler on the TV. That certainly would not stop me watching it, nor would I want to see it edited out - 'Life on Mars' shows 1973 through the lens of 2006, so it's entirely fitting that Savile should briefly feature in an episode.
