He that is robb’d, not wanting what is stolen,
Let him not know ‘t, and he’s not robb’d at all.
– William Shakespeare
Othello, Act 3, Scene 3. When it comes to his wife cheating on him, Othello would rather be blissfully ignorant. He tells Iago that a man who is robbed but doesn’t know it, it is like the robbery never happened. Othello refers to Desdemona as if she were a piece of property that has been "stolen" from him, thus showing his sexism.
