The movement was quite alive when he came to Vienna.
He came from the movement's cradle, Linz.
He was a vocal supporter of its most successful political avatar, Karl Lueger.
He was an admirer of the movement's house philosopher Georg von Schoenerer.
What else do we need to know?
He was a supporter of Los von Rom.
I never said he wasn't. My understanding is the movement peaked sometime around 1905. Hitler would have been about 16. I don't doubt that anything offering potential to sever ties held by Austrian Catholics to Rome would have been unattractive to Hitler, the German nationalist.
