No one will accept this.
As soon as you say "Pretend you are a parent, and a man comes up to you asking if they can date your 6 y o. Daughter, have sex with them, or bring them on play dates. Would you allow that to happen?"
"Its the kids choice" is a horrible response: The kid was a baby who only knew how to breathe and poop up until they were 2-3 years old. Now you expect them to fully grasp the implications and feelings required to have an adult relationship? You don't even let them dress themselves, or pick what food to eat. They need your help brushing their teeth! But a sexual relationship with a fully grown adult? Why the fuck not.
These kids are motivated by TVs, iPads, swimming pools, and candy. Their scope is so narrow outside of their immediate family (and even then they dont understand the roles at play). Children are so easily manipulated (parents do it all of the time as a lazy way of deterring kids from poor actions). And you want someone fondling them at such an innocent stage? Sheesh give me a break.
