I do understand your sentiments, though. (Honestly, in the grand scheme of things, is one pretty, white, American, blonde more important than the Iraq situation, our porous borders, or the upcoming Supreme Court nomination? Hardly.).
However, for a variety of reasons and unfortunately for you, this story has struck a chord with several different groups of TV viewers. I think some of the interest is generated by patriotism; some of it comes from the mysterious "who-dunnit" nature of Natalee's disappearance; and some of it originates with a maternal identification with the tortured mother, Beth Holloway. But regardless of the reason for the interest, as long as this cohort of viewers wants to watch The Natalee Mystery, then good, ol' capitalism reigns and Fox (or someone else) will provide those viewers with exactly what they want.
Now, just p-i-c-k u-p your remote control, go to another channel, and then get over it already. < /rant >
Oh, and I'd also like to point out that Chandra Levy and Lacy Peterson were not blondes, so hair color has nothing to do with the media obsession. :-p
Nor skin color (tone, pattern, whatever) viz. M. Jackson.
