While I'd deplore everything about it, I would note that the most well American fascist website was online when I checked a moment ago. And I'd note that the effort deplatform that site occurred because it was quite well known and truly obscure publications are much less likely to get that treatment (for good or ill).

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.
