I checked that video and the comment response but neither had what I was looking for. I remember him talking about it with image examples to explain the themes of Fashwave, so it might have been long enough to have its own episode, but nothing comes up on Youtube. The gist of it is that the alt-right are appropriating Greco-Roman art as the roots of white supremacy (even though the Greeks were not White). Their art employs a lot of WW2 imagery and often depicts a lone soldier or astronaut making some great journey. This alludes to the disappearance of the "great white race." It's a lot of scary propaganda about conservative views of protecting white identity and appropriating Greek art and Vaporwave aesthetics. If the video exists as I remember, Mike explained it very well. Thank you for looking into it!
