based on your scenario I'd think what a sick perv, however, unless this man in the park had sexual fantasies, feelings and has acted himself towards children he likely wouldn't meet the definition of one
Op, a paedophile is not only a paedophile if they act on it. It's someone with a sexual attraction to children. Irrelevant if they acted on it or not.
This man has has these sexualised thoughts about your daughter. He has sexualised her actions. ThE thoughts he articulated to you, which I don't even want to type out again. About how she was dressed, how she was moving. Those are the things he was thinking when he was looking at her. An eight year old
Isn't that a sexual fantasy? Because it wasn't real was it? It was in his head. Your child is not sexualised at eight as he seems to think. It was simply his fantasy, his feelings, which were wrong, and then That by the age of thirteen, still a child, she'd be Having sex? With many people. And That you yourself were having sex as a child?
Do you really not see it? As said, a paedo is someone who has sexualised thoughts about children. Normal people do not have these thoughts, people who are not paedophiles do not look at young girls or boys and think sexual thoughts.
I understand what your saying in that you think he wouldn't act on it, or you don't think he's sexually attracted to your child, but the fact his thoughts run to sexual when he looks at her, is all you need to know. The fact he attributes sexual motives to her screams at you. The rest he will never reveal.
No normal person looks at a little girl and thinks these things. Even if she's running around in her pants and vest. Even if she's naked.. Normal people don't think these things.. They think of kids as kids and sexual thoughts don't enter their heads. The idea would repulse them.
