"Extremism" - and "The notion of 'extremism'" 

The reason for my recreation of the page under the different title (and for the associated redirect) is that it is at least highly (if, perhaps, not "extremely") controversial to assert, or imply or assume that there actually exists a phenomenon appropriately characterized as "extremism". 

I appreciate that I may not have chosen the best way of addressing this diffculty. I would be grateful if you would advise me accordingly.

Regards,

LJ
