A corollary to Godwin's Law, which usually comes up in political or social arguments. When one party says, "Well, if you don't like it here, leave," they've pretty much terminated the discussion. No one has won, no one has lost. But the conversation is over.

Oddly enough, it is frequently used by all political viewpoints, whenever a differing view wants to change a part of the status quo that the speaker likes.

This statement fails to consider that it is someone's love for a a community that causes them to want to change it for the better.
