The Nazi Twins
There is a lot of insane stuff in this story. The fact that they have a lot of fans is one of them. "White nationalists" is another sickening term being used to describe hate.
Here's link to a sample of their song Victory. The guitarist plays like he/she has two fingers. The story isn't about their music. It is about a mother raising their children to spew hate. They have been tragically manipulated.
