It's because they framed it as childish people doing childish things.

When you think of it that way, it's funny. Even from an artist's point of view, having silly shit hidden in your stuff is amusing.

But then you start to look at it from a different point of view.

You start to remember that this is marketed towards children.

You rationalize it as adding adult humor to keep adults engaged with their children.

But then more context starts to flow in. Human traffickers from Disney. Sexualization of children. More and more of a mental health problem in children and more child abuse than ever.

You forget about it for a few years, maybe.

Then someone makes a bill about protecting children from it until third grade. You might think "that's great! It should probably be for even longer, but at least that's a start!"

But then you see Disney employees and executives start to fight that. Old context starts to re-enter the conversation. You remember the fringes of your thoughts of concern that you hadn't thought about in a while.

Then a Disney executive comes out and says that, yes, they are intentionally putting this stuff in for kids.

And now you have gone from amusement to concern.

It's all about how your point of view changes with additional information, and this is also a big part of maturing in general.
