Regardless, you can't lord a couple of IQ points over anybody, because IQ fails to take into account a lot of factors regarding intelligence. There's plenty of articles available on the internet on why IQ tests alone are useless to determine someone's actual intelligence level. Seriously, a simple google search for "IQ tests inaccurate" will turn up dozens of results. Here's one:
http://www.webmd.com/brain/news/20121218/iq-test-really-measure-intelligence -- The gist of it is IQ can be useful, but is wholly inadequate in getting a good determination on how intelligent someone is. You need multiple tests focusing on various factors to get a better idea.
Ever met the guy who was a logic and math wiz, but couldn't navigate a social situation to save his life and was quite aloof? If he took an IQ test, he'd crush it, but if you tried to socially interact with the guy, you'd wonder how many types of idiot he was.
I do not at all believe in creationism, by the way.
Sorry, I didn't read whole discussion from the very beginning (perhaps, something about "stupid Brazilians?").
But despite of IQ test being not proper tool to measure "total" intellect of the person, it doesn't contradicts with the fact that some "races" performs worse in mathematical tasks whereas other might be better in social.
You might say that "they're not worse, they're just the different", but that it doesn't take away fact that some Brazilians are worse in math that Norwegians (no idea honestly, just to illustrate).
