Grave robbing and the destruction of historical artifacts are definitely an issue, but you should refrain from using the word Moslem, and in it's place use Muslim. The meaning is actually very different, and rather insulting in Arabic:

EDIT: It would appear the "insult" line is a bit of a stretch given how Arabic works, and is perhaps not really that insulting. Yet still, modern scholarship suggests the appropriate transliteration of the word from Arabic is Muslim, not Moslem.
