Ok let's just clear this up once and for all because we're in some deep thread spiral here.

Here's where it all started:

> Me: "No, but he did say that having sex with children is sometimes fine"

> You: "Can you quote/link those instances since the two statements that you quoted don't say that at all."

Here is a statement from Stallman himself summarizing his own words: "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."

So he said himself that what he was saying back then was that in some instances there is nothing wrong with sex between an adult and a child.

This is my answer to your original question. He explained it himself.
