These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Values Dissonance: To an extent, Cartoon Network's sibling channel, Boomerang. The content of Wait Till Your Father Gets Home should easily garner it a TV-PG rating (it would have if Cartoon Network aired it, especially these days, where you have shows like Regular Show and Adventure Time airing proudly with a TV-PG rating), but when Boomerang last screened it, a "TV-Y7" rating was given. Back in the early 1970s, it (much as The Simpsons was in its early days) was criticized for being a cartoon [animation has long been a medium allegedly meant for children] with adult content.
Having said this, it should be noted that the show was originally designed for and for the most part aired in the new 7:30 family slot.
Some of the show's handling of feminism (especially the episode where Irma gets a job at a law firm and the younger, prettier secretary is treated better than the older, plainer Irma), and population control ("Expectant Papa") would be either this or Values Resonance.
What Do You Mean, It's Not for Kids?: This show is best described as All in the Family: The Animated Series. Too bad most people at the time saw cartoons as being kiddie fare (which is true in a lot of cases, but in this case, it wasn't). It wouldn't be until The Simpsons came along in the late 1980s for people to see the light.
