He has the obligation to society that any human being has. I don't think a satirist has any greater obligation to society than a bricklayer or anybody else.
The wit makes fun of other persons the satirist makes fun of the world the humorist makes fun of himself but in so doing he identifies himself with people - that is people everywhere not for the purpose of taking them apart but simply revealing their true nature.
The satirist is prevented by repulsion from gaining a better knowledge of the world he is attracted to yet he is forced by attraction to concern himself with the world that repels him.
The satirist shoots to kill while the humorist brings his prey back alive and eventually releases him again for another chance.
It's funny because I think a lot of it is simply... We've never considered ourselves satirists but because we're on Comedy Central and because we're South Park on Comedy Central we can do any topic we want.
Satirists gain the applause of others through fear not through love.
