Bigoteering
Phenomenal word popularized by Nassim Taleb.
Originates with Tim Ferriss, describes tagging someone (or someone’s opinions) as “racist”, “chauvinist” or somethinglikeit-ist in situations where these are not warranted. This is a shoddy manipulation to exploit the stigmas accompanying such labels and force the opponent to spent time and energy explaining “why he/she is not a bigot”.
Note that it is the true victims of bigotry that are insulted by virtue-peddling bigoteers.
