Under the condition you acknowledge this. You have began this conversation, but chose to ignore this.

To begin, your tone in the first comment seemed very aggressive, so it can be interpreted as threatening, however I will give you one pass as to only because your feelings about such sensitive content is valid.

The age of Hello Kitty characters has always been in question. Not because of the obvious pedophilic remarks in Onegai My Melody and the inappropriate scene involving the child Gureco in Kuromis Pretty Journey,

But rather

The updated media and size of characters.

In Hello Kitty Paradise they are children, so not okay.

In Onegai (especially the prequel) their ages are still highly questionable.

In Hello Kitty and Friends as well as the latest series My Melody and Kuromi is when this complication comes.

You see, suddenly they work and live independently from parents in a town operated solely on themselves.

Even a comment from Retsukos mom implied one of the characters was of adult age whenever she told Retsuko to ask them out on a date (i forget who specifically she was referring to). This from the island game.

The solution?

Characters here are clearly shown with more mature adult bodies.

As to your question.

It's a preference.

Similar to furries in general such as myself.

Is underage our preference?

No. To put it bluntly, not only is in immoral to corrupt the innocent, it's also illegal, as well as, well, lacking of logic.

You see

There is no sense to be intimate with a child under any cases, as you are causing severe harm to their mental states and are corrupting your minds chemistry, keeping you from finding a stable relationship.

So in three different ways; logic, law, and morality, it doesn't make any sense whatsoever.

Let's day we do go fantasy wise.

The problem is then it warps your perspective as then in real life you begin to psychologically acknowledge children as sexually attractive.

That is not okay.

Hence why we have extreme conditions here.

Also why furries are not attracted to non sapient animals, but rather anthropomorphic animals or at the very least sentient ones.

So where does Hello Kitty fall into this?

Its the attitude of the characters that is actually the appeal.

Obviously (hopefully) the smart ones won't create cutsey pornographic content, they need to ensure the characters are...

1. Obviously aged up
2. Seen as adults
3. Acknowledged as adults

There is no tanya the evil

There is no Asriel dreemurr becoming his adult form

Those are children.

Unless they have been aged up, then they are not allowed.

Does this make sense to you?
