Radicalisation is not written on an empty blackboard, what has been written before invites it in.

Re the radicalisatiom of the latest bearded lunatic

Listening to the irksome and ill thought out simplicities of
Fox News token left winger on the 'Five' is extremely irritating

This assertion that this latest  (New York truck atrocity) manifestation of bearded terror
was wholly radicalised since arriving in the US,  lazily assumes that 'he' came
in to the United States in a tabula rasa (empty blackboard) state,

Whereas quite obviously he came in with a set of values inculcated in him (as we all do, Catholic Protestant Jew)   from the culture he was bought up in, these cultural Islamic seeds are ripe for radicalisation, we are all culturally potty trained

This is one of the chief reasons why immigrants are fundamentally unable to assimilate

But we hear the pries of anguish from the moral left, which is essentially is  a religion, secular it may be but but in its fervid beliefs it is undeniably a religion

And who are its saints who send these religious warriors out into the world to proclaim the message
look no further than academia, the Universities et al

This is why the judiciary  and the media are of a left wing bent, for most have emerged from a Humanities education taught by almost wholly left wing Professoriat

So what such esteemed institutions such as Harvard enables one to do is to go out into the
big bad world armed with really stupid thinking (think Obama) who could not even utter the words
'Islamic Terrorism' if he could not even name those all civilised people are fighting - how then would he address the problem?
