*Either her marriage was motivated by ambition (in which case, yes, she's a very successful gold digger) or love (in which case she isn't a gold digger but you can't give her credit for realised ambition either).
You can't have it both ways.*
I wasn't trying to, just pointing out that accusing someone who had become that influential from a middle-class starting point as stifling ambition stuck me as a bit odd.
After all, ambition is all about getting to be the best you can be, there are many ways to do that, and if one involves a loving relationship with gaining power and influence as a side effect then that would seem to be a win.
Unless you think the system that gives you that position is toxic and should be dismantled - I doubt KM does, so I don't think she deserves the personal abuse. She's accused of being dim, but she got to a top University before she met PW, so on her own merits and with all the right grades.
By all means attack the institution of the monarchy, together with the House of Lords and any other hereditary privilege - meritocracy would be much better. But to attack someone who has followed the path that fell before her in such a vitriolic way is as bad as any other form of abuse.
