Friend, the question was why 7 kids was a plus in this situation, not why she was otherwise qualified.
The number of children she has is IRRELEVANT to the description of a United States Supreme Court Justice.
Now tell me, would a "wise latina" with seven children be better?
Having 7 kids develops patience. It also allows you to tune out noise and since she will be surrounded by liberal women she needs to be able to do that.
Now what everyone is forgetting is men have those traits too, after all they have to deal with us every day
