Thoughtcrime of the Day: "Martial Races"

Wiki:

Martial Race or Martial Races Theory is an ideology based on the assumption that certain ethnic groups are inherently more martially inclined than others. It was a term originally used by the British, who observed that the Scottish Highlanders were more fierce in battle than others on the British Isles, and extended this concept to India, where they classified each ethnic group into one of two categories: 'Martial' and 'Non-Martial'. A 'martial race' was typically considered brave and well-built for fighting but was also described as 'unintelligent'.[1] The 'non-martial races' were those whom the British believed to be unfit for battle because of their sedentary lifestyles. Of late, this concept has been dismissed as Imperialistic and based on racial stereotypes.

ie: true but deeply embarrassing to modern sensibilities.
