I will respectfully disagree; there is much more tolerance for pro-Camilla posts whereas similar pro-Diana posts are many times deleted. Personally, I don't think there needs to be a competition between the dead Princess and an alive Camilla; under the circumstances, it can hardly be fair to either side.
I do very much believe that Camilla has brought much happiness to - and has very much settled - the Prince of Wales, and I am glad for both of them. Only good can come from his happiness and I'm sure he will be a better king because of the security of being in a happy and secure marriage with Camilla. That said, it is not necessary to put Diana down in order to raise up Camilla's reputation. I think the more relaxed and content PoW that we all can see does that for Camilla far more effectively than any dissection of the past could ever accomplish. In fact, I strongly believe that if Camilla's boosters were as generous to Diana's memory as they are to Camilla's and Charles' mistakes, then much of the rancour that is left would disappear and Camilla would benefit.
