The more I learned about Charles and Di, the less I thought of both of them but I guess Charles was the worse of the two.
In that time I worked & socialized with a good number of ex-pat Brits in the Washington, DC area. Universals are never accurate but generally speaking I noted the following.
Men were somewhat indifferent to Charles but to a woman, the ladies loved Charles.
Younger ones thought of him as someone to be “much desired”. To older women he was a much loved nephew or some such.
When Diana came on the scene, younger women took on some of the indifference of men.
But it was another story with the older ladies. They pretty much viewed Diana as “that woman”, someone to never be good enough for “their” family.
No matter whoever the real Charles was or even became, the public view of him & Diana deep-sixed his public image.
