I wouldn't change a thing. It's a great big nasty world of scumbag dirty-trick RATs out there and she responds appropriately. You don't defeat evil by being "nice".
In a real shooting war, she could share my foxhole anytime. Seriously. I don't think I can say that about Peggy Noonan (too soft), or Laura Ingraham (wouldn't trust her not to scream and run off).
It's that hard edge, willingness to get mean and nasty, that sets the Philly apart.
Now don't go knocking Laura Ingraham! She could share my foxhole (and anything else!) anytime!
