You're the one applying the double standard.
I'm not assigning blame to Obama for his aunt or for Palin for her daughter.  Neither is to blame for the actions of their family members.
The double standard you are showing is blaming Palin for something she cannot control, but not blaming Obama for something he cannot control.
I clearly stated minor children. You're trying to assign blame for something completely out of Obama's control.
But Palin's daughter getting pregnant IS in Palin's control?  Come on....
It's a specious argument.
Your bringing up Bristol being a minor is specious to this argument, I agree.
