I figure it that way too, CG.
That is to say, I agree with your observation that "Islam" [you can read a whole bunch of other deranged, dysfunctional human attitudes under that head, too, including Western Left Progressivism] is in the business of undermining and supplanting any and all human cultures which do not conform to the seventh-century Mohammed Model of human societal order. As determined by the Will of Allah in every particular, of course.
I do so hope, too, that "all the relics, large and small, in Egypt are protected by someone."
One thing that human history tells you: When you forget the past, it's difficult to discern a living future. And so, the default position becomes an historical past that no one now living remembers. Certainly not in a way that anyone now living has actually learned anything about in, say, the public schools. And so we humans get to repeat the history of which we seem to be deliberately ignorant, now and forever, one more time....
Thanks, CG!
