Bigoteering
The act of labeling a person “racist”, “sexist”, or somethinglikeit-ist in situations where these are not warranted, in an attempt to exploit the stigmas accompanying such labels and force the opponent to spend time and energy explaining “why he/she is not a bigot”.
Example:
If you disagree with Sally on anything political, all she does is call you a sexist, racist, homophobe. Classic bigoteering.
