I would say that’s a matter of the pot calling the kettle black. North Americans and Europeans are pretty overt about whatever sexual immorality they engage in, just as Europeans in times past nearly always were. And western women, even chaste women, tend to flaunt their sexuality with clothing and makeup, just as they always have. But how does one, say, compare the immorality of intentionally alluring clothing on an occidental woman to the beatings, rapes, pedophilia, genital mutiliations, temporary marriages, polygamy, and, yes, homosexuality (remember the “Afghan dancing boys”?) so common in the Islamic world that it makes one wonder whether the Marquis de Sade learned his predilections in the Middle East.
And, of course, when it comes to morals of other sorts, well, to my knowledge there have been no public beheadings or beheading/burnings in the west of late, and nobody in the West (other than the occasional hard leftist) chants “death to (fill in the blank)” at the slightest provocation…and means it.
In comparing the morals of the west and those in the Islamic world, I would say there’s little to be favored in the latter.
