Duchesne, a professor of sociology at the University of New Brunswick, has been denounced as Deplorable by Canadian bien-pensants, although one writer advocated not subjecting him to “campus protests demanding his resignation.” [To silence UNB professor would be to lend his opinion strength, by Gary Mason, Toronto Globe and Mail, January 12, 2015]

In the Salisbury Review he writes:

THE UNDERDEVELOPMENT OF EUROPEAN PRIDE

The most powerful moral assault on European pride and identity is the idea that Western civilisation achieved its greatness, industrial economic take-off in the eighteenth century, and subsequent mass affluence in the twentieth century, by exploiting and under-developing the rest of the world. This is one of the biggest lies inflicted on millions of European students in the last half century. The truth is that the diffusion of European technology has been the ultimate factor responsible for development outside the West.

Stolen Land and the Atlantic Slave Trade

The claim that Europeans built modern America, Canada, New Zealand, and Australia by “stealing” the land from the original inhabitants, sequestering them into reservations, has exacted an enormous moral price upon Europeans. Europeans are a high trust people who believe it is important to treat others fairly as individuals regardless of in-group vs out-group distinctions — unlike other races, which tend to care only about their extended family members within the moral boundaries set by their in-groups. Our hostile elites have exploited this sense of fairness to make Europeans feel guilty about everything their ancestors did in the past. Not a month goes by without a headline that Whites “should return stolen lands to Indian tribes”.

Another claim intended to inflict guilt is that Europeans deliberately introduced slavery into Africa, when in truth they simply made use of an established practice going back a thousand years and were instrumental in its demise on moral grounds. The false story that Europeans were somehow responsible for it has been recounted in hundreds of books and journals.

Remember,  slavery is an African custom—they're still doing it—white people's contribution was first the ocean-going ships that brought it, and its victims, to America, and later abolition.
