I have not read up a great deal on the man, but generally speaking, anti-semitism was fairly prevalent in lots of places leading up to WW2 still, it wasn't until all the dust cleared that I think people got actually human about it.
There is tons of similar stories from England around the time as well, people who didn't know the realities of what was going on in Germany in the lead up to the war who praised Hitler and were going for the throats of the communist movement and Russia in general, the Black Shirts. (Orwell addresses them in some of his essays). It is kind of disturbing really.
