I think the simplest thing is to see these shows as a product of their time. The Honeymooners is considered a classic and is a funny show, but I'm also sure someone in 2019 may not appreciate Ralph Kramden threatening domestic violence, no matter how hard the audience laughs.
It is possible to enjoy a show from back in the day, realize how the show is not very PC by today's standards, but still enjoy the show as a time capsule of a different era, case in point the clip Eric posted. That's not a bad thing. If a network decides to keep an un-PC joke in the show, that's not a bad thing. If the network edits the joke out to appease viewers, that's also not a bad thing. As this thread has shown, they're damned if they do, damned if they don't.
