Antiwar.com reminds us of this charming quote from Michael Ignatieff in 2004:
To defeat evil, we may have to traffic in evils: indefinite detention of suspects, coercive interrogations, targeted assassinations, even pre-emptive war.
Or as Trotsky put it,
As for us, we were never concerned with the Kantian-priestly and vegetarian-Quaker prattle about the 'sacredness of human life.'
Vegetarians, Kantians, priests and Quakers are advised to vote for Rae or Dion.
