Often times a person who rather than being crazy, is merely beyond tired of and fed up with the blatant narcissism, rudeness, ignorance, stupidity, cruelty, fakeness, hatred, etc. of the human race and chooses to detoxify themselves from the vices societies are swimming in to a greater extent than most. Often times recluses have been known to possess extraordinary genius, talent, and/or vision often mistaken as abnormality and eccentricity by the adherents of a culture's status quo.
Standard Sheeple #1: "My brother's wanting social life is an embarrassment to our entire family when we all get together for Super Bowl Sunday and he never shows up. An antisocial recluse the man is."
Standard Sheeple #2: "Dude, what's his problem? If our brainwashed, plastic, shallow, unhealthy, overly-indulgent, mindless, vacuous, and materialistic culture isn't good enough for him then maybe he should go see a shrink and get on some pills to set him back in line with the rest of us normal and adjusted people."
