On satire -

Murky vision... 

The writers of satire comment on human behaviors, beliefs, and traditions through the use of irony, analogy, parody, exaggeration, and caricature.

Satirists employ deliberate ambiguity and obfuscation of the literal and figurative. They often pretend agreement, compliance, approval, or naïveté.

Thus, satire is a toolbox that can be drawn upon to make social commentary and, with luck, it can also be funny, inasmuch as laughter is the best medicine, except for penicillin.
