A ubiquitous form of
fallacious argument, either verbal, textual, or in the form of an image meme, in which one presents the worst possible example of a category they don't like (can anything from political groups to music), and the best possible example of a category they do like, and uses this to suggest a qualitative
difference between the two categories.
From the term "
cherry picking", meaning to pick out a single example of an instance that fits your argument, while ignoring the many more that don't.
