I spent 25 years in the back of vans, touring the world submerged in this culture. No, Green Day had no imprint in our world at all. Yes, these people are a large part of who is behind those black masks.
They are completely ignorant of history and politics. They have zero understanding of issues or legislation. Their left leanings are Pavlovian reflex.
Their love of rioting is simply a fashion that fits their self image. That’s it. No more to it. It’s no different than a Mohawk or combat boots. It’s their idea of being “punk”. It’s the ultimate in posing.
There is no reasoning with them. They are stupid. As soon as there are consequences they will stop immediately.
