Let me make my point for you with some examples. I'll say it slowly.

Vikram Pandit, CEO of Citigroup (an Indian immigrant in the US).

Indira Nooyi, Chairman and CEO of PepsiCo (an Indian immigrant in the US).

Kiran Chetry, Co-anchor of CNN morning show, American Morning (A Nepal-born US immigrant).

Farid Zakaria, Editor of Newsweek International and anchor of CNN Farid Zakaria GPS.

Names ring a bell? Good.

Now, imagine a blonde girl (or brunette, redhead or greenhead, for that matter) walking up to any of them them, saying, "Wow, you speak good English."

Can you imagine that? Didn't think so.

I don't think any intelligent American would dare say that to any of them. Why not? Cuz they would not dare look at them as a subset of immigrants. That would be stereotypical and, therefore, unacceptable. 

They'd simply look at them FOR WHAT THEY ARE and WHO THEY ARE AS AN INDIVIDUAL. That would not be stereotypical.

Fortunefaded, you may think rejecting thinly disguised stereotypical statements as "crying", but I say it's   standing up for respect.

You may feel good and fuzzy when somebody exclaims, "Faded, you've such good English." You may just go along to get along, just so you don't want to be seen as whining. If that's so, go right ahead and be treated differently than those individuals I mentioned above. That's your choice.

And you can make yourself welcome to use supercilious statements like "go cry to your mama". But, you do that to your own peril. When people can't use logic, they take up superciliousness and taunt people.

I'm sure a lot of people feel you're an intelligent man. But your superciliousness has betrayed that feeling.
