National Socialist black metal
National Socialist black metal (also known as NSBM) is a title used to refer to black metal with argued similarities to National Socialism. Some common themes include White nationalism, paganism, mysticism/occultism, and nature romanticism.
The label may possibly be dubiously used as a form of guilt by association label on bands that are not National Socialist (or even black metal), but have some other less politically correct views, such as non-National Socialist nationalism or paganism.
Conversely, the label and associated symbols may possibly be used by bands wanting controversy and publicity, without actually having deeper knowledge of or support for National Socialism.
