Sure, Burning man may have burned a mock up version of a church. Burned a few men. But, Varg Vikernes has burned enough churches to last him the rest of his lifetime. Nothing to be proud of, to be sure. But this is something that happened years ago. We should be glad that it is not happening any longer. But, he had his own reasons.
Many of the churches he targeted were built on ancient pagan ritual grounds. A desecration, and irrespectable act by the church, who has continually made attempts at white washing the indigenous cultures out of the majority of our species throughout its widespread inception. In the attempt to cull the herds, and maintain a dominance over the masses through their manipulation attempts.
Baseline, we all need to have faith. We crave guidance as a species, for the most part. But when we put direction and manipulate those controls to some other purpose. This is where I start to question everything.
All of the photos I have posted here can be seen in the book "Lords of Chaos" by Michael Moynihan (Author), Didrik Soderlind (Author). which you can purchase here. https://www.amazon.ca/Lords-Chaos-Bloody-Satanic-Underground/dp/0922915946/ref=sr_1_2?ie=UTF8&qid=1517543108&sr=8-2&keywords=lord+of+chaos
Or, do some research of your own. The book in itself covers alot more than just the burning, but also the growth and acknowledgement of Black metal on a global spread. It in itself has also led to helping people realize the work and lifestyles of the few artists who were presented within.
