Along with the Phallic Females and Numinous Negroes who have long populated the fictional world that the Bien-Pensants want us to believe is both how things are and how they ought to be*, Precocious Brats are another character set which should be waaaaaay rolled back. This is the child --usually, though not always, a girl-- who is the family Alpha Dog, to whose mood swings, cartoon ideas and snappy rudeness the adults in the family defer. Or whose superior emotional insight puts the oldsters to shame. The "adults" appease, coddle, explain and justify. It's revolting.
Unlike the women and Blacks in these roles, who are far more rare in real life, the Precious Brat is common enough.
A rightwing thinker recently wrote: "We set up entire social systems and ideologies at odds with our most basic instincts, and wonder why the world seems to have lost its mind."
