Sorry to link to YouTube for this, but it’s just such a great example of actual humor from the decades where it was allowed to joke about it.
Perhaps some overzealous reference to the fact that Graham Linehan is a massive wanker, butthurt transphobe. The way you “can’t really make rape/racist/sexist/transphobic jokes anymore”. He doesn’t really make TV anymore. This skit on the other hand, as well as most of Father Ted and The IT Crowd, is perfectly PG.
