If there was any sort of "Defensive" element chart it would be mentioned in game and it would make things overly confusing anyway. Boosting your wind affinity makes you stronger both offensively (element-wise) and defensively to fire, its just that the stats aren't working correctly.
This is the line from the festival details that creates the confusion.
2. Faire chaperones will ask you to take part in the Bombard hunt, and provide you with special heat-resistant swimsuits.

Add to this that SE said Opposing Element for defense against that damage type, and that water is actually opposite fire on the chart, well it's seems to all be stacking up to more than a conspiracy theory lol.
