On the Fact that In 1835 a Band of 500 Maori Warriors Hijacked a British Ship, Landed On the Chatham Islands Just East of New Zealand, and Proceeded to Either Cold-Bloodedly Kill, Cannibalize, or Enslave the Entire Indigenous Moriori Population - a Politically-Incorrect Genocide, One Might Call it

While I'm never one to give the Brits a free-pass (Cromwell, Churchill, etc.), hard to blame the ole limeys for this one (though, yes, try the SJWs most certainly would, if they were to discover this). Reasonably, at least.
