@Foxfyre,
It would give an outcry when Arnold said hew as German - by Germans as well as Austrians.
Well, Hitler referred to himself as Austrian as long as he was an Austrian. And then he was stateless and cautiously didn't refer to his own citizenship at all.
The reference to Beethoven is a German<>Austrian joke.
However, he was a proud Viennese - as well as Mozart spoke in his letters about "we Germans".
However, there were a lot more German national states at Mozart's and Beethoven's time, but only a single one when Hitler was born. As there was only one Austria when he was born.
