Have you actually read the contents of the Guardian article Stallman linked? No? Here come a few quotes:
> If there's no bullying, no coercion, no abuse of power, if the child enters into the relationship voluntarily … the evidence shows there need be no harm.
> A Dutch study published in 1987 found that a sample of boys in paedophilic relationships felt positively about them.
> And a major if still controversial 1998-2000 meta-study suggests – as J Michael Bailey of Northwestern University, Chicago, says – that such relationships, entered into voluntarily, are "nearly uncorrelated with undesirable outcomes".
> Most people find that idea impossible. But writing last year in the peer-reviewed Archives of Sexual Behaviour, Bailey said that while he also found the notion "disturbing", he was forced to recognise that "persuasive evidence for the harmfulness of paedophilic relationships does not yet exist".
So why nobody attacks The Guardian for publishing such statements? Yes, these things are against common sense, against natural feelings, and I refuse to believe them. But Stallman was just repeating what someone else researched.
