Which is to say that net now certainly makes a wider range of views available to those interested than ever before. There's still individual apathy or skepticism keeping people from sample this Niagara but that doesn't seem like the worst. Many people like their platform filtering out racist garbage and hey, that seems like not entirely terrible.
But the contrast is that in a small city in the US in the 1950s, a person would have to physically leave their location to get more "risque" or "extreme" publications of any political stripe.
That free speech allows people who advocate crimes to be watched hardly by itself is hardly argument that this isn't really free speech.
I mean, to some extent, I think it's OK fascist have some venue for their expression. That having such a venue should benefit them rather than being an opportunity for them to hoist themselves on the own petard really doesn't seem like something they can demand.
This is pretty much exactly wrong (the situation is basically the exact opposite). When there were a very finite number of publishers in the English speaking world and self-publishing barely existed, an idea that could not be published would only diffuse by word of mouth. When Henry Miller could only be published in France, his works were only available to a very small number of individuals even if many could be interested.
Anyone banned from every single media site still can create a website, publish on Tor, etc. The inability to get a million followers is far from the inability to get your ideas heard. The argument confuses an inability to make money with an inability to be hear (and feel free to argue about the right make money with incindiary ideas, that obviously has a different implication).
By creating the ability to bypass publisher, the Internet produced a situation where far more ideas could be heard than previously. That situation still exists (for good and less-good). The average person still depends on filters but those filters are voluntary and a substantial portion of people know they can bypass them if they wish. And I'd say present days are also wider than earlier filters.
