 That one doesn't matter so much, imo.  The hispanics I know, live near and married generally believe in a version of the western culture they share with us.  The author says quite clearly that it isn't a racial struggle, but a cultural struggle.  Don't try to make it a racial issue, since that only obscures the problem.  To sum up the entire wall-o-text, it's Islamic culture vs. Everybody Else.
