Guest Steamin' Willie, it's very easy at this safe time and distance to slag off Ratzinger for his membership of the Hitler Youth. That was at a time of intense nationalist fervour in Germany, largely stoked by the punitive terms of the WW1 armistice. The young in their droves flocked to the cause and in Ratzinger's part of the world it would have been virtually suicidal not to do so.

If you want to have a go at fascist sympathisers in the catholic church, have a look at Pius XI's take on the Spanish Civil War or Pius XII's deafening silence in WW2 (as a result of which the Vatican still refuses to release documents from that era) or the obsessively anti-communist John Paul II's haste to beatify hundreds of priests who supported Franko, and others like Archbishop Stepinac, apostolic vicar to the crazed clero-fascist Ustashe who waged genocide in Croatia and Bosnia during WW2.

There is a lot I don't care for about Ratzinger, but he was never a Nazi.
