And this is how we got caught off guard by fascism.
We had two choices, subvert new media or avoid it. Too many people chose avoiding it about 10-15 years ago for the reasons you give, and proto-alt-right groups like Casa Pound took advantage, setting themselves up as the visible alternative to neo-liberalism when the Great Recession started. There are some people who finally understand and are putting videos on youtube, they don’t like it but they need to be where the people are. Preaching to the converted does not help anyone. There are some experiments in putting videos on alternative sites a few days before Youtube, but until Google and Youtube end up like Myspace they have to stay there.
Yes, the Mister Gotchas will be there criticising us, but they understand there is no ethical consumption under capitalism and want us to die off in an impossible quest for perfection.
There is also the mental health cost, when you get people who think they are the only socialist in a world of hostile fascists and indifferent liberals because they can’t find anyone else vaguely like them. I could go further into that, but I need to stop because I am ill.
