White, European, heterosexual, men have set the agenda in western civilization for several hundred years. And reaped the benefits.

It is amusing how defensive and thin-skinned white people get when a writer like this politely points out a few incontrovertible historical truths. The American south, South Africa, India, South America are still recovering from the white-supremacist cultural models that were the norm for centuries in their societies.
Many whites in Canada think that just because they aren't wearing a white hood and carrying a torch the moniker of 'racist' doesn't apply to them.
A quick glance through the comments on G&M stories about immigrants or First Nations  makes it clear that is not the case. 
Calling this column an example of  the "G&M's extreme left wing bias"  is nothing more than anguished cry for a return to the ugly past we are trying to get beyond.
