It's worth noting that the antiwar movement had less in common with hippies than many people think. Sure, there was some overlap - but the mainstream didn't get the idea that hippies were mainly interested in taking drugs and listening to music from nowhere. Most of the antiwar movement was in the hands of students and everday sorts of people - I think the fastest way to offer evidence for that would be the absence of typical hippie uniforms in photographs of antiwar protests. Something closer to the truth would be that the musicians hippies liked listening to made songs about the antiwar movement, and those songs had an outsized impact on the entertainment available in 2020, because as good a speaker as Noam Chomsky might have been, radio hosts don't put him on after The Temptations.

(I'd listen to a station that did that kind of thing, but that's not how it works presently.)
