Godwin's Law of Belly Dance Discussions:As an online belly dance forum discussion about dance styles grows longer, the probability of the invocation of the term "pushing the envelope" approaches one
"For example, there is a tradition in many newsgroups and other Internet discussion forums that once such a comparison is made, the thread is finished and whoever mentioned the Nazis (ed: or has used the term "pushing the envelope" to justify their belly dance performance choices, even bad ones) has automatically "lost" whatever debate was in progress. This principle is itself frequently referred to as Godwin's law. It is considered poor form to raise such a comparison arbitrarily with the motive of ending the thread. "
This may also be seen with the phrase "But I'm an artist I can do (fill in the blank with whatever action is being justified)", and may be followed by the phrase, "You just don't understand" or "You're just jealous".
