European aristocracy ran pretty much on honour culture right through to the First World War. We’re still paying the price. The Prussians were doing it pretty much into WW2. Of course Hitler had no honour and that helped him take over - he could do things that “no Prussian officer would do”. The most intense and longest battle of WW1, the Battle of Verdun, was essentially an honour battle. Strategically it made sense for the French to abandon Verdun to shorten their line; Falkenhayn exploited the need to maintain French honour to lure them into a battle of attrition. But he had the problem that his own side wished to preserve their honour by actually trying to take Verdun.
Getting back to this woman, however, it seems to me that she is simply one of these over-entitled journalists. They treat citizens of their own countries badly enough (in this country doorstepping, phone hacking, pursuit in cars); why would a little refugee kicking be any different?
