In my opinion the racial "issue" in Othello has little, to no bearing. One of the primary considerations should be based on the historical context- a Moor in a venetian town. Moors were once common in Sicily and Italy. Othello is an outsider who utilizes his exotic nature, which means he, by action, is well aware of his social stance given his identity. That I beleive to be the point. Racial comment is a safety net for a lack of ideals. Besides the Elizabethans refered to many other peoples as black, if they were not white- including Italians.
