Is late night supposed to be fair and balanced?

I understand that late night talk shows are more overtly political — liberal, really — than they were two or three years ago. Still, I find it kind of odd that there seems to be a real push for both "balance" and comprehensiveness of coverage, mostly from the right.

This is becoming a regular thing:

Discussions of balance and story choice make sense where the news media — especially media that presents itself as attempting objectivity —are concerned. But these are comedy shows, and most comedy has a point of view. Do they owe the audience (or a portion of the audience) to address certain topics?

This isn't a defense of Harvey Weinstein. I just think this "make jokes about Harvey" push from the right is based on expectations that folks on the right don't get to have. Fair and balanced is for news — maybe — but it's a silly, unrealistic expectation for a comedy routine.
