Beyond functioning as a boundary psychology we have also noted that disgust is an expulsive psychology. Not only does disgust create and monitor boundaries, disgust also motivates physical and behavioral responses aimed at pushing away, avoiding, or forcefully expelling an offensive object. We avoid the object. Shove the object away. Spit it out. Vomit.
"So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth." Rev. 3:16
