Maybe I'm the crazy one, but I personally consider any group that worships nazis to be an extremist group. If they were in the US and hadn't done any kind of "extremist act" I would feel the same way.
From what I've heard in interviews with fighters from other units (Lindybeige ones come to mind), which is hearsay I grant you, they're not Nazis, much less worshippers of Nazis. A few bad apples, or some such.
Ukrainian Nazi groups apparently always had problems making connections with other Nazi groups because they were all pro-russia
