Sneering Imperialist

Sneering Imperialist is a perk in the Fallout: New Vegas add-on Honest Hearts.

Effects
Sneering Imperialist provides a 15% damage boost and a 1.25x multiplier to the player character's V.A.T.S. chance-to-hit when attacking members of certain groups, such as tribals, raiders, Fiends, and Great Khans.

Although the perk's description only mentions raiders, junkies, and Zion's various tribals, which non-player characters the perk affects are actually determined by the non-player character's "race" (referring to a game-specific setting rather than perceived racial makeup). This covers a number of groups/factions in their entirety:
 * Fiends
 * Freeside thugs
 * Jackal gang members
 * Freeside locals
 * Viper gunslingers
 * Caucasian Sorrows
 * Caucasian Dead Horses
 * Caucasian White Legs

In addition, a number of other groups are partially composed of members of the specified race designations:
 * Freeside squatters
 * Great Khans
 * Refugees
 * Wastelanders

Finally, a few named non-player characters are covered by this perk:
 * Dixon
 * Joshua Graham
 * Oscar Velasco
 * Pretty Sarah
 * Melissa
 * Violet
 * Daniel
 * Motor-Runner
 * Cook-Cook
 * Driver Nephi
 * Duke
 * Genaro
 * Regis
 * Salt-Upon-Wounds

Behind the scenes

 * The image and name are a reference to the era of Imperialism, where soldiers of European superpowers would invade and conquer what they deemed as "uncivilized" societies in faraway lands.
 * In color, the soldier standing on the dead Fiend is wearing the traditional uniform of a British soldier.
