Not just "reality TV" but especially "dramas" - lies (for example, sexual egalitarianism) are on display all the time, in the name of political correctness. It becomes another form of indoctrination.
Even escapist fare (action series like Burned Notice) involve artistic license with respect to their portrayal of the real world. (How much deviation from reality can a story feature before it is no longer realistic?)
Comedies might seem to be the exception but even they have reality as a standard in some respect - can there be comedy if the standard is not true?
