It takes a Lefty fascist to think this is bad. It's the perfect encapsulation of the attitude of every tribe, family, nation, and baseball team on the face of the earth, and it's completely charitable and normal. What are kids supposed to think? That their own folks are nothing special? (Are they allowed to think that their Mom is prettier than any other woman?)
In particular, let us encourage men to think of their wife as the prettiest woman ever.
A perfectly healthful attitude.
