Ironically one of his fan’s “support pages” is a great source of just that.

> “In 2006, Stallman published a controversial comment about the intention of pedophiles in The Netherlands to form a political party[1]. He wrote, I am skeptical of the claim that voluntary pedophilia harms children. People today don't think that a prepubertal human being—a child—is capable of understanding all the implications of sexual activity (in some cases this may be so even after puberty). So in widespread social opinion, the concept of “voluntary” does not apply.
In the same article, Stallman writes, [...] stretched by parents who are horrified by the idea that their little baby is maturing. This is not totally improper, it encompasses the immense diversity of beliefs about age of consent and morality across cultures.
As for laws, in the United States the criteria for determining age of consent and related issues differ across jurisdictions, some of them have raised the age of consent as recently as 2017 and 2019. Furthermore, the United States seems to have a double standard when it comes to these laws, since marriage of a child with an adult—even much older—is allowed under certain circumstances; we believe that this seriously disregards children's wellbeing in favor of some other “convenience.” Lastly, it may be surprising to some that age of consent in the US is 16 in 34 States”
Then the actual “defense of Stallman” bit is that he changed his mind or at least said he did… thirteen years later:
Whatever the reasoning that led Stallman to write those statements, the fact is that later he changed his mind:
> “14 September 2019 (Sex between an adult and a child is wrong)
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.
Through personal conversations in recent years, I've learned to understand how sex with a child can harm per 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.”
Note the date and remember this VERY late “change of heart” coincidentally took place one month after Epstein died and became the current sensation he remains.
That’s from an attempt defend him, and ironically the site is full of documentation of the hideous things he says and believes.
