Is this divisive jock/preppy/nerd/skater/gangsta shit still going on 23 years after I left high school?

There will always be popular extroverts and unpopular introverts.

Can we stop this "Introvert" BS? An "introvert" is someone who will tend to keep their thoughts to themselves. Nothing more. This "the extroverts are the sports guys and the introverts are the intellectuals" is completely made up and people will not like you more or less depending on wether you wear your heart on your tongue or not.

An "introvert" is someone who will tend to keep their thoughts to themselves.

That's not correct at all, and it's funny because you're so confident about it

although both the popular understanding and current psychological usage vary. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reflective and reserved behavior.

That's not how they're defined, just typical manifestations of the underlying personalities.

Introverts emotionally recharge from alone time, extroverts emotionally recharge from time with others.
