I tend to disagree...this track had always been controversial since its release in 1981 but it was never meant as a glorification of fascism nor was being taken for it generally (with excepton of the far-left). Not even the neo-fascists had embraced the song since Gabi Delgado (RIP) was of Spanish origin and the line "Tanz den Jesus Christus" ("Dance the Jesus Christ").
BTW...I love these sounds and I think...nah, no Reichskriegsflagge in my house. ;-)
