Can you even read? I did explain that in the very first sentence, by mentioning that your scenario would not be legally possible.
And I was just wondering, because US Americans online are often extremely prudish and self-centered, which matches your attitude.
According to your own comment, Stallman literally said "NOT INDISCRIMINATELY", which to me can only mean Romeo and Juliet laws and/or only after mandatory sex education. Do you fucking know what words mean? Your scenario is completely made up in your head and not something Stallman advocates for, at least not according to the quotes you yourself provided.
So this scenario is something that YOU made up. He also said 14 according to the quotes provided, not 12. Interesting how you're moving the goal posts.
And defending the age of consent to be 14 is not "pro-pedo", and there is no such thing, because as I just explained, pedophilia is a state of something that can't be okay or not okay, favoured or not favoured, it just is. Also it refers to children below that age, so you really need to upgrade your vocabulary and learn the definitions of words in it. Defending this age barrier is called having a fucking brain. So yes, attacking people for saying that 14 is a reasonable age of consent, especially when also mentioning Romeo and Juliet laws, is extremely prudish.
