I'm gonna steal a comment from a Reddit user:
But in reality Palin's family are a major issue, because she wants to make everyone in the United States like her family. She wants everyone to follow her rules on family planning, upbringing, religion etc.
I could not have said it better. If her platform wasn't based on busybodying, her family catastrophe wouldn't matter. But she wants to impose her irrational beliefs on others, and we are not going to let her.
