> I am skeptical of the claim that voluntarily pedophilia harms children. The arguments that it causes harm seem to be based on cases which aren't voluntary, which are then stretched by parents who are horrified by the idea that their little baby is maturing.

We are talking about what stallman has written. The above is what he wrote. The distinction he's drawing between "voluntarily pedophilia" and "involuntarily pedophilia" is one that I don't believe exists. Particularly because "grooming" is a common tactics of pedophilies.
