<p>There's nothing racist about talking about white people's chances to get into Brown. But so far, there has been one comment that implied racism, and it wasn't particularly vindictive either. It was more of a dissertation type proposition. Frankly, calling anything on this looks prepackaged.</p>
<p>I don't believe Middle Easterners are considered to be caucasians. I believe they are considered semitics (which means more than just Jewish, despite the term "anti-Semitic"). Iranians, though, are caucasian. Aryans, to be more specific. Northern India is also predominantly aryan caucasians. Southern Indians are part of a separate "race" called "dravidian", though I don't know what the term really means. </p>
<p>Also, the term "white" has its own complcations. "Hispanic" not being a race, all those in South America not Mestizo are classified as white, though not always as caucasian. White refers exclusively to skin colour. </p>
<p>To whoever said it, sure, race mixing is common. Race mixing may not be common everywhere, but it is abundant where the social dynamics are such that there are no cultural restrictions on it. Take a nation like Brazil. Or New York City. Or the city where I live, Vancouver. That interracial mixing is common here is the biggest indicator that biological speciation is not what is at work, unless you seriously contend that the populations of Brazil, New York, and Vancouver as a whole are cladogenically speciating on their own. Which is of course ludicrous. </p>
<p>People's preference for their own race in mating is not indication of speciation. In the past, people had more of a preference for their own ethnicity, which would have meant that each nation was speciating. Also, by this reasoning, the preference of blondes by many guys - not shared by me, but in any case - would mean blondes are a different race. Most animals are not social - Drosophila flies certainly are not - so selective mating, where it occurs, is much more clear cut. (Does a queen's mating with only its own drones make each beehive its own species?) But one thing's for sure. If you want to count one instance of preferred choice in mates, you have to count all of them.</p>
