What is the most controversial "denomination" within your religion?

I would say that the most controversial denomination within Norse Paganism is the Neo-Nazi Pagans. They use Norse symbols for their rhetoric and regular Norse Pagans are afraid of wearing those symbols outside because of them. They're also the reason why many individuals think that Norse Paganism is a White Supremacist faith. The most famous Group are the Wotansvolk and Asatru Folk Assembly.
