After reading I think you are blowing this out of proportion by stating that "it says it all". There is a section there about his political beliefs and he says his main belief is that tech-monopolies should be broken down and society should be governed on a smaller scale. I think half of HN readers would agree with some version of that. And about "the SJWs" - he only says that people are asking him to make video about them and he is not going to do that.
Maybe I don't know what alt-right is but I don't see how this is alt-right. Just because he uses the term "SJW" ? I don't use it but I know what it means. You apparently do also. That doesn't make us alt-right, right?
There isn't much alt-right about that specifically, but it's clear wording that the alt-right has been using online for years. Talking about "SJWs" controlling the media and universities (and in the very same paragraph saying every "normal" person wants them "gone") and calling things you dislike "soy" are both plays in the years old alt-right playbook. If it walks like a duck and it quacks like a duck...
I have noticed that people commonly referred to as SJW often consider everyone who is not them to be alt-right.
And yes, people sharing social justice values do obsess over it and it shows.
Anecdotal example: random article brought to me by sliding android home screen to the left about new Foundation series spent more than half of the volume addressing the diversity of the cast and lamenting that on-screen sex was showing only heterosexuals.
This can be said about almost any article about any piece of media directed to me by Google, from which I do conclude that SJWs, indeed, control the media.
(I have no personal experience with the US universities, so I can't say anything about them being controlled by the SJWs)
Ah, the blessings of the Google-free Android experience get proven once again by this counterexample of Google - or rather those working for Google who are in control these feeds - pushing their agenda onto unsuspecting (...?) victims.
May I suggest removing whatever stock distribution you have and replacing it with e.g. LineageOS, doing away with Google services - use microG [1] et al if you need something which depends on them - and dropping whatever "news aggregator" feed is offered by third parties? Use something like Nextcloud News [2] and add the feeds for a number of publications, both corporate as well as alternative, from all sides of the political spectrum. Compare how events are reported between them and form your own conclusions. Also give up on the hope of non-political culture reporting from corporate media, this seems to be one of the most heavily politicised areas with nearly all publications slanted towards the "left" side of the political spectrum.
