The group chanting sends shivers down my spine.
Reminds me of Hitler Youth events.
After I watched your video clip I was inspired to look for YouTube videos of Hitler Youth parades. I found many and was amazed at the amount of neo-Nazi contributions which I found. Within only 1 minute of search I saw everything from holocaust denial to praise and sentimentalism for Hitler Youth. Much of it was from Germany, but some of it looked like it came from USA.
Scary!
