I have had a related conversation with a handful of 2e adolescents on the autistic spectrum, and have often taken the studying-an-interesting-natural-phenomenon approach, combined with the pragmatic concerns of how this affects attaining one's personal life goals. Emotions may be experienced as unnecessary and harmful to this specific individual, but the empirical fact is that the vast majority of humans operate in the emotional realm. One's options are
1) to abandon all situations that may be affected by other humans,
2) live in a state of perpetual conflict and frustration with them, or,
3) study their behavioral patterns, and learn to manage interactions with them in a way that is mutually functional.
Humans are not unlike other natural phenomena or areas of study (weather, projectile motion, integrated circuit design), in that there are patterns and generalizations that can be made, with a fairly high level of predictive value. Like weather, it's not 100%, but still not random.
