Oh For Heavens Sake!
Neither I nor anyone else commenting here "pathalogically hates" Diana!
We can simply see the way that the press would treat a child named after her. The name has become iconic (your reaction shows that) and the press would make so much of how this child will have to "live up to the image of her grandmother who, by the way, will be 37 years old for ever.
Diana had two names and the other would honour her and her family just as well and without the baggage.
As for Earl Spencers daughter: What other british Earl has produced a daughter who's birth and naming warranted a full page article in at least two daily newspapers???? Had he named her Charlotte Frances nothing would have been made of it. He named her Charlotte DIANA.
