I'm an American millennial so I have no idea what the British press' take on it was, but I think now maybe we can see it more clearly for what it was, which was basically a leftist, vaguely hippie-ish reaction against old right wing nationalist sentiments. They embraced music from all over the world, especially Africa, and they were very interested in the avant-garde, which fascists would've dismissed as "degenerate."
I know what your first reaction might be since it's vice and for some reason they got the lispy guy from Rancid to narrate, but this is actually a pretty nice documentary on it:
