I also think there was gender swap in 3rd rock played for laughs, but I might be misremembering gender differences for an alien. I also don’t recall the episodes so not sure if it was just poking fun at gender as a whole.

Similarly, I think scrubs has some references that may be unpleasant but on the whole they tend to be good or thoughtful when dealing with subjects that at the time weren’t always represented well.

Unfortunately, a lot of older shows have unpleasant jokes. We just have to realize that jokes were a way to discuss the taboo and if we didn’t have those jokes back then, we might not have the progress to today. That’s not to say we want them now but we should judge the media on the knowledge and morals of the time.
