To our knowledge this is the first time that this particular set of fractures within American society have been mapped. And it is likely to be the last time as well, so don't blink.
The map reveals that America seems to be largely pro-pizza with the red dots of pizza spreading across the landscape (the Midwest and Northeast seem particularly well endowed) like a rich and robust tomato sauce. Perhaps there is something after all that everyone can agree upon. (Although the unity behind pizza would likely break down over a fight between "New York" and "Chicago" styles.)
Moreover, there are a number of clusters -- represented by green dots – with more references to guns than pizza. We're not quite sure what life there is like (as we live in a particularly large swath of sauce) but it does give one pause for thought. Are these patches of green olives? Peppers? Jalapeños? Pesto? In any cases, these clusters are predominately rural areas – where apparently there are more guns than pizza.
Lastly one sees a few scattered locations where strip clubs are more popular (we're looking at you Las Vegas) than either guns or pizza. Much like the token scattering of pineapple that one is forced to endure on pizza (there's always one person who suggests it!), strip clubs represents a decidedly marginal activity in the aggregation of human experience illustrated in this map.
In any case, this post has made us hungry so we're off to grab a slice.
