Appeal to privacy

​If-by-whiskey

If-by-whiskey is a fallacy named after a speech given in 1952 by Noah S. Sweat Jr. It is used to conceal a lack of a position or to dodge a tough question. 

If, by whiskey, you mean the brew that causes so many problems, then I'm against it. But if whiskey means the oil of conversation, the philosopher's wine, then I am certainly for it.
