Now available in all good stores. . .
where to not agree to stock an item suggests that your store is not good, or:
All rational people agree that. . .
where to refuse to agree suggests that you are not rational, or:
Those who can, teach.
(a slogan used for encouraging people to become teachers) which suggests that if you aren't teaching a subject you are implicitly "worse" at that subject.
Obviously, all of these are subtle phrasing tricks that may be used casually or quite deliberately.
Is there a term for this type of phrasing?
