Nope. You are interpreting this to be binary, and definitive, rather than conversational and observational. It is about a common pattern of behavior, not a label about everyone.
When most Americans can only speak one language, don't have a passport, expect familiar food and English in other cultures, think there's only one "right" way to run society, and celebrate under-education, then we earn the criticism. In these aspects, we are relatively primitive and simple minded. In other aspects, we aren't, and my friends in other countries willingly acknowledge them.
When we Americans can't take a joke, can't take feedback about our culture and be appreciative of it as a learning and growth opportunity, we deserve the label of "overly sensitive, insecure, emotional snowflake."
