Antanagoge

An antanagoge (Greek ἀνταναγωγή, a leading or bringing up), is a figure in rhetoric, in which, not being able to answer the accusation of an adversary, a person instead makes a counter-allegation or counteracting an opponent’s proposal with an opposing proposition in one's own speech or writing.[1]

It may also refer to placing a positive outlook on a situation that has a negative connotation, such as in the following examples:
