Dick Cheney should have publicly stated he loves his daughter and always will. But her public actions have brought shame and disgrace to the family and he cannot support her.
I think where things went wrong is when Liz and the family showed support for Mary. Did they go to their "wedding"? I would not have.

Agreed. Without that support, they might not have felt validated and might not have chosen to confront Liz publicly.
