AMERICA IS A ____ NATION
The Texas Republican Party platform (download here, see p. 8) "affirms that the United States of America is a Christian nation." (You can imagine how welcome non-churchgoers feel in Texas.) In her column, Cathy Young skewers this formulation and the defense that the party is merely saying Christians are a majority. She notes, for instance, that it would be equally accurate to declare that "America is a white nation."
Inspired by Cathy, Electric Commentary suggests some other, equally data-based descriptions, starting with "America is a fat nation." Contribute your own in the comments section. I'm still looking for the stats, but I'm sure America is a brunette nation (though L.A. is a lot more brunette than Dallas).
