Is Art really the only form of expression that should not be ridiculed? I think artists especially should have a sense of humor about their art; and Art with a capital A. Self deprecation is a healthy thing, it’s what makes comics funny, the same is true of Art; all art forms. Nothing should be too ‘sacred’ to be lampooned. I say tear down the temples to rebuild them stronger. The Conceptual Art movement takes strides to accomplish this.
As they say, this is nothing new. A favorite example: Duchamp’s L.H.O.O.Q.?
