Okay, so then let us clarify for those who may not know the difference.
Melting pot - when everything gets mixed together and each element looses its unique quality. You really can not differentiate one component from the other.
Stew / salad / mosaic - when each component comes together, but they each retain their own unique quality.
So where does that leave people like Madonna - an Italian-American Catholic from Detroit, who during her early music career incorporated a lot of Soul and R&B sounds into her music, but then moves to England, tries to fake an English accent, and converts to Kabalah (?sp). Now is she a melting pot or a stew?
