My inital answer was “It depends on the details.”
So I’ll spin out some details for you, but the answer is always contingent on which details we imagine:
Assuming she was like Bristol in every detail known to the public I would ask her to explain how she thought she had the right to impose her lifestyle choices on her children—if she thought so little of my fatherhood that she thought her children could dispense with one of their own.
I can’t imagine a response that would make me think that adoption still wasn’t the best option, UNLESS her (and, given her demonstrated selfishness up to that point, most likely my) attempts to identify adoptive parents failed.
If we couldn’t identify a good pair of married parents to adopt the children, then I would support her decision to raise the children with our assistance, but if suitable parents were identified I would indeed fully support the adoption of the child to those parents.
But in the end, she would still be my daughter and I would not permit her and her irresponsible decisions to become a burden to society if I could prevent it.
Burden to society?
Ms. Palin is not a burden on society; if that is your analogy to "if you had a daughter".
Sometimes crappy things happen in all families--you deal with it the best you can. No one is immune, no matter how good a parent they think they are.
Sometimes great (blessed) things overshadow those crappy things.
We will only continue to agree to disagree. I am fine with that.
Now really am off to go read a book.
