24 here:
Some good points. And I respect your point of view just like I respect anyone here with a sensible and/or well reasoned point of view here.
In terms of what kind of animation I enjoy personally, I've always enjoyed sophisticated, intelligently planned, and mature animation personally (it's the kind I plan on making one day), but even with that being so I have great respect for old Disney films (The Lion King, The Nightmare Before Christmas, Tarzan, Hercules) and 90s saturday morning American animation (Kids WB, Fox Kids, Disney Afternoon, etc.). Those to me represent the pinnacle of children's animation, in terms of technical execution. They're visuals are good, the timing is right, and they don't pander to the young demographic, but instead do what any decent children's programming or cinema would do and appeal to everyone, not just kids, even if they get labeled "children's animation" even though they clearly appeal to all ages.
If one is going to make children's animation of the aformentioned variety, that has universal appeal and appeals to kids, and young or old adults of all ages, then more power to them.
However, on a personal note, my current personal preference, now that I'm older, lies with adult and mature themed animation on television or on DVD, either from Japan, or Europe or America, or all three. (i.e. Ghost in the Shell, Aqua Teen Hunger Force, Boondocks, Samurai Champloo, Cowboy Bebop, Fullmetal Alchemist). This is to say nothing of all of the "children's shows" or as I like to call them "all ages" shows like Avatar and Naruto and DBZ, etc., that appeal to people of all ages, which seem to appeal to an entirely new demographic altogether: the 8 - 24 demographic, give or take a few years.
In terms of mature or "adult" animation programming, I've always said about anime (ever since I found out about it around 1997 or so, somewhere around there, and doing a bit of reading up on the Japanese market) that I believe Japan sets a good animation industry example with anime, and always has for a while now, that animation in Japan is not simply thought of as a "children's medium" and hasn't been for a long time now. The proof of this fact lies in the way Japanese animation narrative is told: With the mature, intelligent view in mind. Clearly Ghost in the Shell: Stand Alone Complex is not intended by its makers for the same demographic shows like Johnny Test or Spongebob are.
In terms of content and demographics, those two kinds of shows are polar opposites. One appeals to mature and sophisticated and serious spirits, i.e. drama. And the other kind, ones of carefree and whimsy, i.e. comedy. It may sound strange in written form, but it's true. Those two genres have been around for much of history. But it's only been recently that the animation medium has gotten complex and technically superior enough for the two two genres to emerge in the medium of animation in any real noticeable way. Call it what you will: "Action", "Drama", "Suspense", it's all the same thing. But the former style wasn't anywhere near as visible in the 1940s as it is now. That's for certain.
