You seemed to allege that the current (say, last 20-30 years' worth or so) of violence by Muslims in the Middle East, was due to expansionism or encroachment by other powers, and was as such, a justifiable reaction.
I was pointing out that rather, it is Islam which has been expansionist and violent, long before any of us were born, indeed back to its inception, even before the Crusades.
And that hostage taking and slavery is nothing new from Islamists, either; and that they have been troubling the United States long before 'Western Imperialism' -- indeed, even when the United States themselves, were just free from being colonies themselves.
