The phrase "Have you stopped beating your wife?" is an example of a loaded question. This particular phrase is a canonical example used in the book The Power of Logic (C. Stephen Layman) and is often quoted.
There is a particular post where this phrase was used to point out a logical fallacy.
I personally don't feel that domestic abuse is appropriate in any context on StackOverflow. Be it that the SO community is largely male, and are not often the recipients of domestic abuse, many may not agree. 3 moderators tacitly or overtly approved this kind of language in the above post.
My question is two-fold. Is a phrase containing domestic abuse appropriate on SO to point out logical fallacies? Second, would similar made up phrases like "When did you stop stripping for money?" be appropriate?
