Did you even bother to read the emails or at the very least the article? This misconception is exactly what's being argued there, that Stallman said something clearly different.
> Ignoring a legal age of consent
By doing what, raping someone underage? Or rather expressing his opinion that it's ridiculous that when in one state the age of consent is 16, in another one it's 18, and yet people are judged morally and criminally for failing to distinguish between these two? So basically what you're saying is that possessing a non-standard opinion and criticizing existing laws should make you a non-person. I believe you'd feel very much at home in the USSR, the communist party had the same ideas.
