Astounding. Are you referring to those "spiritual" religious-types, who suppress their natural instincts so much that they end up so repressed they sporadically have intense outbursts of "sin" like chastised nuns, monks, priests and clergymen usually do?
To deny one's human animal instinct is to deny life itself.
We're highly intelligent beings, yes, however, we're more than people trying to pretend we don't do anything animal-like such as urinating, defacating, ejaculating or enjoying sexual experiences.
