I have been teaching in elementary school for over 20 years and I’ve NEVER seen elementary age boys acting effeminate, or elementary girls acting overly masculine. I’ve seen girls who are physically active and aggressive (what we used to call “tom-boyish”) and boys who are less aggressive, but who still act very much like boys.
I occasionally see girls holding hands, but it’s always been obviously friendship with no hint of sexuality at all. I’ve never seen boys beyond the kindergarten age holding hands. Ever.
At around 4th or 5th grade you start to see some bit of attraction by boys and girls for each other (usually in the form of teasing, chasing each other, but not overt romance).
Whenever there is any hint of a romantic anything, the typical response is universally “ehew, yuck!”. Whenever there is the extremely rare occasion of something that suggested same-sex attraction, the response is quadrupled in the “yuck” category. My only conclusion is that this “gay” or “lesbian” behavior must be a learned behavior. I just have never seen it in the hundreds of thousands of kids I’ve taught over the years.
The libertine goal is to make the sexualization of children be seen as normal. They then can be “allowed” to act out their sexualization and thus become targets of desire or permissible to interact with by adult predators.
Homosexual targets are developed in early teen years in this manner.
