I don't know anyone else's inner world obviously, but reading between the lines of what he said it sounds like that era of German history disrupted his family enough that there is no romanticisation going on.
Plus he told me about an occasion where he confronted some stupid teenager who decided to go to a nearby shopping centre in a reproduction Waffen SS uniform and rather forcefully told him to leave when the police said it was distasteful but they couldn't do anything about it (before the bans on publicly showing Nazi iconography).
I think he is a standard Lib Nats voter that has the usual amount of mindrot from watching a bit too much SkyNews (more than 15 seconds qualifies as far as I am concerned).
