Ghosting is when a person has irreconcilable differences with social values that he begins to avoid interacting with society.
Ghosting happens because society demands conformity and dissent is punishable. Thus, unable to object and unwilling to conform, the individual choose to cut or reduce his ties with society. The person considers society to be hopeless.
Ghosting may include emmigrating to another country. As such, ghosting is the furthest possible display of rejecting society and highest level of MGTOW.
