Well considering in 1956 the Austrians who were polled for a survey after learning about the horrors that happened during the Third Reich, over half of them still considered themselves to be part of the German nation.
However, instead of trying to reverse the burden of proof, it is your claim that the Austrians never considered themselves to be Germans and you have failed to provide any reliable evidence to support that whacky claim.
I thought that we were discussing the German-speaking Austrians.2 There are no proofs that after 1867 most inhabitants of Cisleithania (which were Slavic ) considered themselves as Austrians .
Why would they have done that? The Austrians despised the Prussians and the feeling was mutual.3 There are proofs that after 1867 most inhabitants of Cisleithania considered themselves as non German .
2 examples :
the number of inhabitants of Cisleithania that volunteered in 1870 and in 1914 to fight against France was insignificant .
in big parts of Germany ( less in Bavaria and Würtemberg ) each year the population celebrated the victory of Sedan on 2 September ( Sedantag ) .This was not done in Cisleithania .
If the 4th of July is not celebrated in Britain,that is a proof that the majority of Britons do not consider themselves as Americans .
4 After 1806 what you call wrongly Austria was a Slavic state, not a German state .
And it is not so that because Franz Jozef claimed to be Emperor of Austria,the inhabitants of his state considered themselves as Austrians .Kafka did not consider himself as Austrian, neither did count Badeni who was PM of Cisleithania !.
You're bizarrely trying to discuss the non-German lands that the Austrians ruled over. Why? We're discussing the German-speaking Austrians and the German territories.
Franz Kafka was from Bohemia and of Czech-Jewish descent, why would he have thought of himself as a German?
