“For some reason, right-wing extremism is almost always seen as an atomized, individualistic threat that is difficult to monitor and is somehow different [from Islamic extremism]."

Um...you then go on to describe exactly why.

"Exact membership figures are unknown, as new groups have cropped up and then splintered or dissolved in recent years...Canada’s far-right is very fragmented...
Right-wing extremism has not been as significant a problem in Canada in recent years. Those who hold such extremist views have tended to be isolated and ineffective figures....these groups have few members and that the members often change groups or belong to several groups at the same time”

.. posters and pamphlets and "incidents"...

vs. a very well organized, international group that has committed dozens of mass murders...

And gimme a break..."welfare chauvinism – the idea that the state should provide social welfare to its own citizens rather than foreigners" is now an extremist idea?
