"...the comparison is valid.."
I'm sorry, but I've seen a good bit of Rome and a good bit of Naples, and the comparison is not valid.
Is there a large city on the planet that does not have it's grim areas? Yes, Naples certainly has them, and so does Rome (but the Termini area is not one of them, in my opinion). Both cities also have areas that are very lovely.
It is a completely pointless comparison offered by someone who has spent very little time in Naples, who has seen only a small part of the city. She dismisses an entire 2,5000 year-old city largely on the basis of anecdotes about bums at the port having harassed her daughter. That is why it constitutes Naples-bashing.
If someone were to say a lot of nasty things about Rome without having actually spent any real time in the city, that would be Rome-bashing.
Those of you who are befuddled by my reaction are probably unaware of Lupaling's consistent rain of negativity about Naples in the Naples forum. As someone who loves Naples, it does get under my skin at times - not because she doesn't like Naples, but rather because she's never even given the city a chance.
