Some care has to be taken in selecting such examples.
Thus, suppose we were to argue that the Boston Globe applies a double standard to the city of Boston, subjecting it to unfair criticism. The argument is plainly absurd. Obviously, comparison must begin by setting as a baseline the ordinary level of coverage of affairs in Boston, Seattle, and Karachi in the Globe, and the reasons for the general selection. It must also consider such factors as the level of favorable coverage of the three cities. Correcting for the obvious errors, the theory of self-hating Bostonians quickly collapses.
