However in the above example you can at least argue that the parents raised the unruly children and should have had better control of them or been stricter in their upbringing.
The actions of a parent or adult sibling are an entirely different manner. Meghan didn't raise her father or half-siblings into the people they became and, given that they are all older than her, has never had the authority to impact their behavior. Children should never be punished for being unable to control their parents or siblings because that isn't their job.
It's akin to saying a verbally/physically abused person doesn't deserve sympathy after awhile because they haven't managed to convince their abuser to stop. As someone who grew up with an emotionally manipulative father, the implication that at some point it's Meghan's fault that she hasn't "fixed" these toxic relationships is hard for me to accept. No matter how much you want to heal those relationships and play happy family, it's a two way street and if others refuse to change or consider themselves in the wrong (whether they're in denial, or enjoy this manipulative behavior) it simply won't be fixed.
That's indeed the mature, well considered and ideal consideration.
But as you know, that's not how the world works.
I cannot and will not presume to speak on behalf of the British and Americans, however I live in a monarchy too, so I can understand at least some of the public sentiments.
Meghan's family are not just embarrassing H&M, they are as a consequence embarrassing the BRF and I imagine embarrassing many, if not most Americans and Britons in particular.
And
people don't like to be embarrassed! Certainly not repeatedly, let alone for years to come. If that happens then at some point there
will be a reaction directed against H&M. Is it unfair? Oh yes! But it's a human reaction.
The problem is of course that the constellation H&M is still on probation. And this detracts.
Of course a lot of people will rally around H&M in sympathy, but will they continue to do so, if this goes on?
To put it brutally: Meghan in particular hasn't earned enough public credits to ensure that the majority will continue to form a cordon around them. They are not QEII, not even approaching W&K (yet) around whom people
will rally.
Right now H&M are getting a lot of sympathy and good will up to their wedding, however once the honeymoon is over, they will have less credits in the bank than they had just a few months ago.
So, will this be serious for H&M? IMO no, provided H&M do a good job, and why shouldn't they?
But Meghan's family will repeatedly pop up and chisel away at the what H&M have build up from time to time.
Right now they are milking the cow big time and the next time the family will make a spectacle of themselves will be when Meghan gets pregnant, and certainly when their child will be christened. I don't need a crystal ball to predict that one!
