Hmm, I got that one wrong. It’s an organization that’s been around for quite a while promoting the sexualization of children, and has been influential in sex-ed in schools. I’ll see if I can find the name, there have been articles about it on FR and I’m sure I’ve pinged at least one, but maybe several years ago. They’re of course totally evil.
Is this the one you mean?
