This fellow quite neatly encapsulates nearly everything that is wrong with the Millennial Snowflake generation. Most generations outgrow the stage of their life (approx: 13-25 for females, and approx: 15-27 for males), where you automatically know *everything*. A good chunk of the Snowflake generation, however, are permanently stuck there, and not only that, they have the unshakable, cocksure, and monolithic self-confidence that exists independently of both logic and mere facts.
Your explanation is the end result of all those Participation Trophies kids got for showing up.
NO MERIT REQUIRED.
