Can't find it now, though.
> "Many years ago I posted that I could not see anything wrong about sex between an adult and a child, if the child accepted it," Stallman wrote. "Through personal conversations in recent years, I've learned to understand how sex with a child can harm per [sic] psychologically. This changed my mind about the matter: I think adults should not do that. I am grateful for the conversations that enabled me to understand why."

I have no real sympathy for Stallman besides his FS movement, I find the man disgusting for many reasons, last but not least his hygiene, and his statements about pedophilia were another part of this disgust (albeit he later condemned his own words and apologized). But taking his words out of context to say that he is a rape apologists is no more than Twitter-level witchunting.
Just because you can marry a child in some parts of the world doesn't mean I'm not gonna consider sex with a 12 years old anything but rape just because it doesn't break local law.
Is having sex with a 12 years old despicable and morally unexcusable? Yes. Is it rape? Unless you're willing to say a 12 years old doesn't have a will at all, calling it rape contradicts your own definition.
