In days gone by the “diverse constituencies” adhered to being in America. “Progressives” now want America to lose her identity instead. America, the Melting Pot of the world has become America, the Boiling Pot.
Some liberals talk about how America is not a melting pot, but instead, is a salad bowl.
They talk approvingly about how there is lettuce, tomato, croutons, bacon bits, etc. all combined together to make a unique flavor of America. Or some such claptrap.
