...and as far as I understood, that comment was not completely retracted, but amended to change the "age bar" to 14?
On the other hand, the freedom of speech does only guarantees that you can tell what you believe openly, but never ever protects you from the consequences of your actions.
Just because some communities believe that entering puberty is enough for these things, it doesn't make it right or harmless. I can find many examples of wrong things which range from funny to atrocious but harmful at the same time.
I'm a big believer of GNU and GPL, and use the four freedoms as the blueprint of what I develop or participate in, however being right and wise in these subjects doesn't make one free from consequences of other actions one may take.
So as a result, linking to a comment telling that being 14 is enough for these things doesn't put the words into context or vindicate the person saying these things.
I may equally say that these words should be punished with a mouth pear (which I do not support in any way, honestly), but we decided that people should be punished in more honorable, better and ethical ways as a planet.
Then, just because some communities prefer mouth pear to this day, it doesn't make the device a legitimate and correct way to punish people.
So, your link to a comment doesn't provide anything in context. Just adds another person who believes in things which are heavily damaging the person who receives this treatment.
