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:

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:

Behind the scenes
The image and name are a reference to the era of Imperialism, where soldiers of world powers generally from Asia, Europe and America would invade and conquer what they deemed as territories in faraway lands to increase their wealth, power and prestige.
