That's the conclusion they reach based on their own analysis of the information they have, free of any prejudice on their own part.
It goes something like this.
"Sweet little one, you are a beacon of joy. You inspire me in so many ways."
"Sweet big one, you are a beacon of joy. You inspire me in so many ways."
"Let's spend as much time together as possible."
"I'll play with you like it's the last day I'll ever see you. I'll act as your personal protection and always keep you safe, but I won't place limits on your freedom to learn and grow. I'll treat you with the same respect you see me treat each and every other person in our environment, and then some. You will never hear me give a false answer to any question you ask. You will learn so much from me and have so much fun with me. When we make eye contact and laugh together, we will be in pure ecstasy. And you will know all the while that I am learning just as many things, and having just as much fun as you are."
"I love you SO MUCH!"
"I love you too. You are beautiful and special and never let me make you feel otherwise. You must tell me immediately if I ever do ANYTHING that hurts your feelings or makes you upset so we can talk about it and resolve it with mutual caring, because I CARE ABOUT HOW YOU FEEL."
"The same goes for you too. I care about how you feel, too."
"If you ever need anything I'm there, no matter what. You can talk to me about absolutely anything and I will NEVER judge you."
"Okay, I believe you and I trust you. Big one, can we cuddle now?"
"Of course we can cuddle, little one. I love being close to you."
"I know. I love being close to you too."
"Big one, I'm kind of jealous when I see you with another girl."
"Little one, I'm kind of jealous when I see you with another boy. But I won't let my jealousy make you feel bad. You are free to be with whomever you please. I don't seek to control you in any way."
"Big one, did you know I had a crush on you?"
"Oh, I see."
"It's okay for us to have a crush on each other, we just can't date."
"Big one, did you know you're really cute?"
"Oh. Thank you. That's very sweet of you to say."
"I know you like girls my age instead of girls your own age."
"I suppose I can't deny that."
"I like boys your age too."
"But older boys and younger girls aren't allowed to be together. It's against the LAW."
"SO WHAT? That doesn't make it wrong, because you don't choose who you like. We should be together and just not tell anyone."
"What if they find out?"
"They won't find out. Don't you trust me?"
"I trust YOU. It's THEM I don't trust. If they found out how I feel about you...."
"But who CARES what they think?"
"I care, because they're in charge of when and how much I get to see you. Already they think I don't say NO to you enough."
"You say NO the RIGHT AMOUNT. You say NO when it MATTERS. So who CARES what anyone else thinks if you know you're right?"
"You just need to trust me."
"I do trust you."
"I know how much pain you go through. I know what other grown-ups think of you. I don't care. It makes me love you more. They don't see you for who you are. I do. I know you could NEVER hurt me in a million years. And I want you to love me FOREVER."
But you don't understand. You don't know how cruel people can really be.
Just you watch....
SEXUAL PREDATOR SENTENCED TO 25 YEARS IN PRISON AFTER LURING, GROOMING, AND SEXUALLY ASSAULTING A LITTLE GIRL.
OR, OR, OR, they had consensual sex after years of mutual feelings which eventually turned into a romantic affair.
(And he wrote half a dozen songs about the whole thing and when he channels the pure emotions he feels towards the girl through the words and notes of the songs he has the cosmic power to form live connections with his listeners, bringing himself to tears mid-song from the sheer cathartic release while they stare speechless in awe because he's actually touching their soul... among many other traits of his that should, at least in theory, be affording him the benefit of their doubt - especially since one of the main ways he connected with her in the first place was by creating beautiful music with her... and the purity and power of that type of connection should translate to other endeavors....)
(But, yeah, since he's sexually attracted to little girls he's probably just a psychopath, and let's make sure he's forced to stay away from any children and that he more or less dies alone.)
