The same is also true for native-born Americans. All of us can claim equally to be Americans, but all must acknowledge a shared set of beliefs and mores. America has always been diverse. Still, it will not do simply to condemn diversity, any more than it will to embrace it indiscriminately. There is much diversity that is valuable or at worst harmless.
Some diversity is good, and some bad.
Here are my ten, aimed as much at the native-born as the newly arrived. Don't disparage anyone else's race or ethnicity. It may seem odd to begin the list with this one, but actually it's not. On the list of things we don't tolerate, intolerance deserves a prominent position. If we are to be one nation, we cannot criticize one another's skin color and ancestors.
