Um, no.  Look again at what I was responding to:  
That's flat, absolute, as presented in the text.  There's no qualifiers, no wiggle room.   He didn't say, "doesn't strongly promote," or "rarely promotes".   It is a complete rejection, as written.  Very difficult to oversimplify, given it's extreme simplicity.  Please, inform us on how I oversimplified or otherwise mis-characterized this very simple statement.  
All I did was paint a picture that might suggest to someone who has a little empathy that perhaps it isn't so absolute.   I did not say this was the *only* contributor, or that the US was the *only* country on the hook for dealing with it.  Nor did I assert any other absolute in my response.
But, you turned that into *solely* anyway.  
Yes.  But, the counter to an absolute does not need to be another absolute - all it requires is a single case.  Recognition that these things aren't all-or-nothing would allow us to quibble over how much each issue contributes to radicalization, and how cost-effective each preventive measure is.  
I recognize that countering an absolute with another is common on the internet, but it did not happen here.  Until such time as you recognize that, your position is a strawman, and does not otherwise call for rebuttal.
