I am not even going to bother reading this piece as I am too tired of the misuse of the word radicalism.   Please elites, learn what 'radical' means!!!! 

It means getting to the root of an issue.  It is from the Latin and Middle English.

 Do you honestly think that is what people on the far right that vote for Trump do?  Or, their brethren that become Islamic terrorists?   Are they really trying to understand anything?  Or are they merely low effort (ergo not radical) individuals that promote violence and austerity.  

That is the complete antithesis of 'radical'.    Learn your language please....!!!!!
