Beloved, by Toni Morrison
(Auto-generated)

made her believe she could discriminate among them.
Part 2 *

discriminate = recognize the differences
With that education pat and firmly set, she dispensed with rancor, was indiscriminately polite, saving her real affection for the unpicked children of Cincinnati, one of whom sat before her in a dress so loud it embarrassed the needlepoint chair seat.†
Part 3

indiscriminately = done without recognition of differences

standard prefix: The prefix "in-" in indiscriminately means not and reverses the meaning of discriminately. This is the same pattern you see in words like invisible, incomplete, and insecure.

Definitions:

(1) (discriminate as in: suffered discrimination)
to treat people of different groups differently -- especially unfair treatment due to race, religion or gender
(2) (discriminate as in: discriminating taste)

(3) (meaning too rare to warrant focus)
