Well, ignoring the fact that her family collects massive income from our hard earned tax to live in their life of luxury they also control massive swathes of gold, diamond, silver mines etc... where slave labour is still exploited, it angers me for example when you see Princess Beatrice on TV today at the London Marathon talking about helping Africans when here family/establishment is the primary driving force behind the suffering of certain areas of Africa.
I can also mention her, and her husbands eugenicist beliefs, for example her husband wrote the forward to a book ' If I Were an Animal' that he would liketo be reincarnated as a deadly virus and wipe out swathes of the human population... very nice chap indeed.
Again, this whole 'nice old lady' charade is promoted by the media and has no bearing on the reality... why do we never see the queen doing things that Diana did? because she hates plebs and is not a nice person.
