It's terribly put. The American concept of freedom of speech has nothing to do with access to public forums but rather is a limit on government action against your ability to run your own forum (newspaper, etc), and if you consider that when the Constitution and Bill of Rights were actually written, most Americans had significantly less forums. A few newspapers made up almost the entirety of public forums when the right was written, and none of them were forced to publish political content they disagreed with.
In fact, when you realize that the internet has provided more forums for free speech than any technology in history, it beggars belief to suggest that there are less forums now than before.
We are at the ultimate highpoint of access to freespeech forums in American history, and to suggest otherwise is nakedly ignorant conservative propaganda pushing an emotional angle against technology corporations who enforce common sense rules against violence, terrorism, and hate speech on their private networks.
I maintain that until Fox News or conservative talk radio is mandated by the government to stop suppressing my free speech rights to have access to the network to say whatever I want, that Facebook and Twitter should not be forced to support insurrection and violence masquerading as free speech.
It's hard to understate how outrageous this lie is. It's like suggesting "folks today have less access to electricity than at any point in American history". It's such immensely stupid lie that how could anyone fall for it?
