We have, or are supposed to have, freedom of speech. This grants us our own discretion in that freedom.
Discussing gender and sex in a kindergarten setting would be considered by most to be inappropriate. We conduct ourselves appropriately and limit freedom of speech all on our own with common sense. We have trouble with freedom of speech when we have individually lost connection with common sense. Those wishing to regulate free speech wish to usurp our moral compass on the issue and would have us abandon our individual right to freedom of speech to their discretion.

The access to information is really at the heart of this problem with free speech today. I believe that we historically had the same problem we see today as at the time of the invention of the Gutenberg press.
The access to information became available to the general public way back then. Information that had been hidden for centuries was now circulating throughout the masses. Not only that but new ideas, true or false, could spread from community to community in no time.

Is today any different than what occurred back then? The power structure was threatened at that time and it is threatened today by the quick transfer of information. We are learning that the political elite have many secrets about their activities. We fill the void with our own conjecture and are called conspiracy theorists but some of our "conspiracies" are proving true.

When the printing press became common, rumors that were spread about the King despoiling the coin by alloying the precious metals with base metals became general knowledge which the King would declare false and you could not spread this rumor. Old coppernose (Henry Vlll) was exposed. That's a story in itself. The coins minted at the royal mint made the nose of the King a little higher than the rest of the coin and that part of the coin, when it wore down, exposed the copper beneath. So a lot of people knew of the degradation of the coin and of course Gresham's law, where bad money will always replace good money,meant that the old coin was horded and the new coin used as currency.

Anyway, the power structure back in the time of the Gutenberg press was Monarchs and the Roman Catholic Church. The press allowed for the spread of new ideas in the church and schisms started to form. We had Lutheranism, Calvinism, Anglicanism and other forms of protestantism that no longer believed in the infallibility of the Pope in Rome. Kings had to be more accountable to the people as well.

The internet and social media poses the same threat today to the powerful elite and they are scrambling to quickly centralize power before their plans blow up.
