So you'll ignore the 70% racism and IQ bullshit (IQ is ironically a very dumb way to measure intelligence) and pick out what you like, and use that to defend him? Oh, but you won't "address the snipped bits," because there is no way you could defend him on that.
The guy is a racist, sexist, raving lunatic. Nobody needs more stupid like that.
So which is it? Do Latin Americans not have lower I.Q.s on average or is the fact that they have lower I.Q.s irrelevant? You can't have it both ways. I said having brains and using them wisely are two entirely different things. And before you scream "Racism!" again, you should know that my daughter whom I love more than the whole world is half Mexican. That word is used to shut down discussion by people who claim to be objective.
Is it racist to say that groups in different environments develop different characteristics over time due to natural selection?
Yes I can have it both ways. IQ is irrelevant to me because of the research I've done on it, but you are treating it as relevant so you can judge other races, so it's a dumb argument on two counts.
As for that "my daughter is half mexican" argument, that's not shutting down shit. It's just a variation on the classic "but I have black friends!" nonsense that racist people use to "prove" they're not racist.
Your last line is not at all racist. The easiest example is the closer to the equator you get, generally the darker the skin pigment gets. An adaptation to deal with differences in exposure to the sun. That has absolutely nothing to do with intelligence, though. Natural selection should tend to favor the more intelligent of the species, regardless of skin color, so natural selection will tend to make all races smarter over a long period of time.
So some environments couldn't disproportionally benefit the intelligent more than other environments? Never mind. Fuckin drop it, Dude. We're way off topic.
