I thought the title of this post was an exageration, but after seeing that dialog...
Don't ask the user negative questions
More often than not you'll confuse that crap out of the poor user; users are already too scared of answering questions to still bother them with the opposite of what they want, it's a simple and basic rule, but I still see a lot of software (and developers) that use negative questions/options for data input.
The most common use of negative options is probably disabled
Label X visible?
Field X Enabled?
Label X Invisible?
Field X Disabled?
That subtle change makes it much harder to answer the question correctly; so prefer Enabled over Disabled, Visible over Invisible, Active over Inactive, etc
The same concept applies when naming variables or methods, in very few cases the negative is a better option, so just go with the safer option, it's easier to process, we are used to answer "positive questions" and the opposite usually causes us to think which makes things not intuitive
