You're correct that an alternative viewpoint exists in the media.  However, here in Canada, I'd say that the overwhelming amount of educators, (the author of this article being an example,) are unified in pushing a left wing ideology that misrepresents history and vilifies other points of view.  This creates a population that is more indoctrinated that it is educated, which is reflected in our elected representatives, government policy, and much of the media.   Despite the media you mentioned above, I believe right of center viewpoints are being pushed further to that margins.
