I counter that that simply doesn't matter. Consider: if (1) ISIS doesn't like it, (2) Arab speakers use it derogatorily, and non-Arab-speakers either (3) don't know the etymology, or (4) understand the derogatory intent, I think Daesh achieves the goal of linguistically delegitimizing ISIS as a "state".
