I agree.  Mr. McKenna has written so many articles advocating the abolition of Canada's supply management system -- and therefore the destruction of Canadian dairy farm industry and 
the rural economies it supports -- without giving any space for counterarguments.

 In the end, I have to wonder whether his zeal is solely attributable to his devotion to now out-dated  free trade orthodoxy or whether he has some more personal pecuniary interest. Shares in Wisconsin dairy industry perhaps? Reatives in New Zealand?
