Without exception, every band I looked at either had obvious nazi or white supremacist references in the name, or a cursory search found it to be related to Nazi or Christian Identity groups. A bunch of them are German so there's less easily accessible information, but still, they're basically all nazi metal bands, not just metal bands.

Edit: moving my other comment into this one, as others have mentioned, the band you linked changed their name because another band with the same name was a Nazi metal band. Perhaps that's why only the name shared with a Nazi band is on the list. (that other band presumably being https://www.discogs.com/artist/1917747-Sturmtruppen)
