Maybe I'm wrong here, but I don't think most people who say they "hate stories about kids" are accurately describing their problem, so telling them they're wrong to "hate stories about kids" isn't going to do anything for anyone.
(It isn't anyway! The flip side of "let people like things" is necessarily "let people not", folks.)
The thing is, most media primarily about kids is also designed for kids, and there's — you know, it's one of the defining qualities of the difference between kids and adults — there's a significant cognitive difference between you, an adult and a kid? (I'm presuming you're an adult.) Also, a lot of kids' media serves an agenda which I can't straightforwardly describe as "educational" because that's taken to mean "didactic within a formalised academic subject" but...y'know: intended to teach, however indirectly. To model life lessons. To impart points of socialisation. Sharing is good! Teamwork helps! Be nice to people! Don't kick your friends in the face! Kids' media has particular characteristics, is what I'm saying, and you honestly can't fault adult people if the thing they actually don't want is media aimed at low on cognitive development/literacy curves, and/or media designed to secretly teach children how to grow into reasonable people.
Don't hate stories about kids!
Like Otter said, they're mostly there to teach kids things!
(altho I'd like to posit that there's a lot of adults out there that should probably watch them, because they don't seem to have a grasp of the basic human decency these stories usually attempt to instil)
Stories about babies however, are absolutely nauseating and should be banned.
