As much as I like rms, I find it very difficult to move past his comments on child pornography[1]. [1] https://stallman.org/notes/2011-mar-jun.html#4_June_2011_(Bo...
If a 16 years old girl sends nude photo her 16 year old boyfriend in Germany, it's fine. If she does the same in US, he's pedophile. This is what RMS was talking about.
"But even when it is uncontroversial to call the subject depicted a 'child', that is no excuse for censorship. Having a photo or drawing does not hurt anyone, so and if you or I think it is disgusting, that is no excuse for censorship."
