I don't deny what you're saying about Kinsey, but it would be false to deny that sexual arousal/stimulation is part of even a child's experience, and this is WITHOUT perversion or corruption due to outside forces.
I'm sure any number of people on this site could give examples from their life of kids they've seen(or were) that somehow were sexual, even if it was a very innocent and experimental act--and NEVER with adults.
That is not to justify or defend Kinsey's research or conclusions, merely to point out that children are not sexual tabula rasa who activate at puberty. This is well-known, I would hope, by now.
I think people are objecting to the idea of doing "experiments" to "prove" that notion.
You are seeing through your own lens. The propensity is there in all children, but all pre-pubescent children certainly aren't sexualized. It ususally happens early because of either having been molested, or seen others sexually acting, or been exposed to sex on TV or movies.
Pre-pubescent children are certainly curious and maybe play "Show me yours and I'll show you mine" but sexual acts? That is not normal for little children.
You may be sincere, but you're at the very least showing poor judgment by choosing a thread about Kinsey to share with us that humans begin to experience sexual arousal before they are adults. And you're shocked, shocked to find this results in people calling you names.
What decent person would ever have the "sexuality" of 5-month-olds cross their mind, without Kinsey having perverted and corrupted, both directly and indirectly?
