The nuts image is a PR game, period. SWA is not desirous of a rolling cockpit circus, they only wan't a reliable airline that doesn't crash many airplanes. All the folks I've seen hired at SWA, if not on the "straight and narrow" were normal people, who applied in normal ways, who had kept their nose clean, and were of reasonable, pleasant temperment. The "nutty" guys all came back from DAL without a job.
