that makes sense, but I think joining in when it starts to look advantageous is even more of an indictment of passively or actively endorsing the party's agenda. 'jumping on the band wagon' are enablers who are often times the force and power behind a movement.
That said, this was the same period when many world notables thought this national socialist invention had something going for it. Ford, Kennedy, of course the Windsors, Lindberg, Brundage and others said some fairly positive things about what was going on at that time.
Sorry, folks, the date was actually May 1 1937. It was the same day that many other royals joined the party (e.g. "Mossy", Georg Donatus of Hesse, his wife Cecile and brother Ludwig). According to "The Royals and the Reich" certain people were not able to be members up till then, and this was the first day they were allowed to join. Alexandra's daughter Alexandra had already joined in 1933, so maybe she was a more enthusiastic Nazi.
Otherwise I agree with you, Herr Kaiser, that a passive endorsement of the Nazi agenda is every bit as bad as an active one...
