We are instinctually discomforted by things that are unfamiliar to us - the appearance and behaviors of the homeless, the physical state of the visibly disabled, people of other nationalities, etc etc. We also are instinctually uncomfortable with public sex acts (sex is something to be done where you are safe and can’t be interrupted says monkey brain). We are instinctually uncomfortable with acts of excess, as in a community with tight resources, their excess means less resources for the rest. Extend those to the point they become absurd, and what do you get?
