Un-reportable racism?

So in a match I just played, a guy was suffering from major salt.

One of things he kept doing was talking trash about people from the United States, now I know that that's not a race but neither is Pakistani , however if someone says "XXXX Paki !!!" that's considered racism and yet, if they say the equivalent of someone from the U.S. that is not considered racism.

Of course I reported this person but I don't know if the report will do anything because I've noticed that racism against the U.S. tends to be accepted because .... well, ironically, racist reasons.

To clarify I am not from the U.S. but I consider all racism bad and thus, I report every instance of it. My question is; Will a person that is racist against people from the U.S. be punished to the equal level as someone who would do the same to another group of people? let's say to africans, or middle easterners.

WOW HOLY MOTHERLESS GOAT, literally as I pressed the button to make this thread, this occurred; http://imgur.com/feFji6w Racism is not tolerated I see. I'm very glad.
