Their point is that Benghazi is on par with Clevland and The Arias trial. Non-substantive cultural freak shows, not something a SERIOUS PERSON should be concerned with, like gay marriage or more FORWARD-looking pursuits. It was their way of telling their viewers it was cool NOT to pay attention to Benghazi.
I see what you are saying here, but either I am not as smart as I thought I was, or I was blinded by the stupidity of making a comedy skit from 4 Americans losing their lives (and a woman gruesomely murdering a man, and a man keeping three women prisoner for ten years while he raped them, beat them and murdered his own children).
It's probably just me though.
