In this instance I would define it this way.
Little girl notices something different. She has no thought on it but curiosity.
Mom noticing the little girl hasn't formed a disgust for this practice is afraid now not that her child will just accept it but could now practice it.
She has teach her child this behavior is something to be feared. How? This will get you banned from paradise like someone with a bomb will get banned from the airport. Fear
Now the little girl will carry this fear with her and her own sexual development. But wait there is more! She is gonna let this other girl in on the fear using the punishment reward scenario.
Jw homophobia boils down to if we don't hate what Jehovah hates then we accept it. The child was a blank slate for discrimination in this case and mom demonstrated how to draw fear on that slate and bigotry.
That is how I define it here.
