They wanted to keep the fighters who were willing to stay and not be Nazis. Changing the name is pointless it’s named after the Azov Sea, and cleaning house can be done without changing the emblem, especially as it was only a Wolfsangel and not a Swastika. Had it been a Swastika I’d be 110% on your side but it isn’t. As already said: Random people just don’t associate the Wolfsangel with Nazis, you pretty much need to be a Nazi or Antifa to recognise it.
And since when is Jägermeister a Nazi drink. What’s next, Berentzen Saurer Apfel?
