And actually, to follow up on my question (does anyone remember ANY such opinion about comparable Canadian matters making it past an editor)...

... well, ask yourself a second question, was the Canadian article in question sitting beneath a paraphrased version of today's actual headline, as in: 

"Will Liberal Party take long to make Canada less white?"

If that headline above an opinion piece makes you bristle, if that headline seems glaringly offensive, if you are feeling outrage against the words you see in print...

... then ask yourself a third question:

When it comes to opinion pieces, why is the Canadian media so comfortable hurling provocative and pungent spit-balls and molotov cocktails on issues of immigration and race IN AMERICA to provoke stark, uninhibited discussions about race and immigration matters in AMERICA...

... but not comfortable using the same approach with immigration and race matters in Canada?  

It is totally bizarre!
