Britfish, my heart sinks when I hear Frankie Boyle (who I think is usually geniusly funny) make jokes about children being abused.
Hitler is fine to make jokes about it helps us to come to terms with what he did. He was one person who is also now dead, he was the very visible head of a sinister political party who made the killing of millions of people into a social policy.
Paedophiles on the other hand are hidden in our own society, they look and act like everyone else. They could be family friends, brothers, uncles, mothers and just recently they've been proved to be nursery workers. They're the enemy within. Who can blame anyone for wondering about the people who come in contact with their children? Not me.
Making jokes about the understandable panic (that's been amplified by the press, and kind of rightly) parents feel when they trust other people with their children isn't funny to a lot of people. If you take offense at other people not finding it funny, perhaps it's time to turn off your computer.
