The important word, Jim, is 'potential'... & I would reply that, yes, those subject to certain conditioning, as e.g. culturally-based ~~ by in-family, late-in-life, fully arranged without the option, marriage demands, say ~~ frustration of certain natural expectations, will have a greater 'potential' for seeking their satisfactions illicitly than those whose cultures do not inhibit natural expectations in the same way. Which is not to say that any more than a small minority will be likely to succumb to such illicit seekings.

You on the left of the political spectrum are, after all, adept at blaming poverty for crime; but if I said that you are ∴ accusing all poor people of being 'potential' criminals, I think a sharp rejoinder might come back to me, of precisely the sort you deserve for your pertinacious and wilful misunderstandings of the points that Keith, pertinently quoting other authorities, is making with regard to the Islamic culture in its relation to marriage expectations.   

Pray extrapolate...
