Yes, I have seen these videos. Even more interesting are some of the comments that accompany them. There are definitely people posting and commenting on these videos that are Neo-Nazis and Nazi sympathizers. There are also Germans who, while not Hitler fans, had fathers and grandfathers who fought and died for Germany in World War 2. I have exchanged messages with some of both stripes. From them I learned of the thousands of German captives who starved to death in the Rhine Meadows camps near the end of the war. I think we have to be careful when condemning scenes of the Wehrmacht goose-stepping to martial music as hate speech. Despite, or due to, their sins, Germany suffered horribly in the war, losing a generation of young men, along with countless thousands of civilian casualties. While I shudder at images of the swastika crackling in the breeze and the smirking Fuhrer in his limousine, I feel tremendous sadness when I look into the eyes of the doomed German soldiers.
My opinion anyway.
