So, I See This Bit of Tomfoolery on the Internet

So, someone allegedly did a survey of "pies for the holidays." And they came up with this bullshit.
Key Lime is the favorite pie for Thanksgiving in the "Deep South."
What kind of Tomfoolery is this?
Now, I like Key Lime....But for Thanksgiving?  And do folks in California know what sweet potato pie even is? And where is pumpkin? 

Map two is closer to reality.....But in Mississippi, they like apple, equal to pecan?
And where is sweet potato?
