I'm sure most here have read about the destruction of Sufi shrines in Timbuktu. Is Islam so intolerent that it cannot even respect the different sects of it's own religion? If it cannot tolerate sects of it's own, how can it respect those of other religions?
It's worth noting that they destroy sites which are valued by local Muslims, in fact this is the reason they destroy these shrines, specifically because they are unhappy with the fact that local Muslims venerate these shrines and their saints.
Also, for anyone who would like to enrich their knowledge of this wider subject, there is a fascinating ammount of information about the problem of archaeological preservation in the Middle east conflict zones. There are professional Muslim archaeologists and scholars who fought a hard battle to preserve their heritage, and in fact what is considered world heritage of the highest class. Furthermore there are examples of the general public during the Arab Spring in Egypt physically protecting the Cairo museum.
So there is definitely a lot of grey area here, anything from destruction of sites, to looting of sites, to scholars efforts to preserves the sites and to increase awareness about their importance to the general population.
Ironically I presented a paper about this specific wider topic recently and focused on the contemporary events in the Middle East, including the Arab Spring, the American presence in Iraq, and the Israeli-Palestinian conflict... so in the happy occasion that anyone wants a short read let me know.
