An example is someone who is a serial adulterer who publicly accuses someone else of being immoral and untrustworthy for sexual infidelity in marriage, while presenting his own adulterous betrayal of former spouses as excusable because he believes that he is exempt from the same moral standard he accuses others of breaking, and entitled to exemptions because he is better than other people. Double standards are often paired with this kind of entitlement and skewed moralistic behaviour.
That's an interesting angle. I'm more familiar with the type of double-standard set by a third party where a rule is declared to apply equally without exception, but
tacitly treated otherwise. So in this case, the person is using a form of "special pleading" along with (dubious) criteria to
propose a double-standard be applied to him.
