Interesting collection of thoughts about Qutb.
Like you, I have never seen a church social that mathces the one Qutb describes. And I have been actively involved in one church or another since I was born.
Of course, the churches I attended at didn't seem to need officially organized "single's nights", nor did the leaders brag about marriages caused by church events.
On a more serious note, I've run into several claims that the Muslim responses to Christianity look more like responses to various heresies or misunderstandings of Christianity. Your post on that subject gives a better explanation of the historical forces at work than the others.
