It gets so much hate because it almost always turns into a sexual creep fest. For example, adoption. If you've ever tried being adopted either as a joke or because it's what you're into, you'd know this. A lot of the time people are adopted the owner or 'parent' has another agenda in mind. It's quite disturbing when the adopter starts to flirt and cyber with the adoptee. That gets a little out of hand and crosses a few major lines. Imagine that same thing happening in the real world. It's pretty disgusting whenever you think about it. What I'm trying to say is almost all clean intended role play usually ends up becoming sexual related somehow. Which is what makes roleplay in general look bad.
