No one is saying that the daughter should go the rest of her life accepting the lie. What I'm saying is that she can't be expected to completely abandon relationships that's she developed over the course of 2 decades in 2 weeks, 2 months, or even 2 years just because the mother wants it to be that way.
You're conflating issues. No one in this topic is saying that the mother's anger isn't warranted. It absolutely is, but all that anger should be directed at Williams. None of it should be directed at the daughter. The daughter is basically the biggest victim in the story, so how can you cosign the mother taking any part of her anger or frustration out on her?
And yes, we are speaking from logic, but just because you're emotional about something doesn't mean you can't do the wrong thing. If someone kills your mother, and you hunt them down and kill them, you're likely going to jail. You'll get a lesser charge and shorter sentence than most murderers because everyone would acknowledge your mental state, but you'll still be punished because you're still in the wrong. The same is true here. The mother is wrong to believe that her daughter should or could abandon everything she's ever known instantly. She's also wrong to let any of her frustration and anger be directed towards the daughter.
I can tell the mother that if she actually loves that child, she needs to give that child the time adjust and not try to force the issue and then browbeat the child when things don't go as desired. That's not something a good mother would do to her child. Again, I've never been in the mother's position, but every parent learns that sometimes you have to put what you want to the side for the benefit of the child.
