Why is that poisonous? It sounds like Fraktur was rejected by Nazi Germany which isn’t a bad thing at all.

Do you know anything about the Nazis, other than that they are bad?

They used Fraktur extensively before 1941 and it's closely associated with Nazi imagery. This is all explained in that link I posted.

I prefer to think of Lie groups, but it's rife in the Nazi propaganda of the 30s, official documents etc.
