Mansplaining is a silencing tactic used by feminist against men who disagree with feminist orthodoxy.
Mansplaining is attributed to ingrained assumptions about the superiority of men's knowledge and opinions compared to women's.
Mansplaining is a form of everyday incivility in which women are presumed ignorant, powerless, or just plain wrong because men know better.
Mansplaining is a micro-aggression, a practice of undermining women's intelligence, their contributions, their voice, their experiences, their knowledge, their expertise such that it undermines women's feelings of self-worth and results in their deciding not to speak.
Mansplaining is a form of derailing in which men will interrupt a conversation between women to explain something to them about the subject, whether or not the men know anything about it and regardless of the men's level of expertise in the topic.
Mansplaining is more than just a conversational inconvenience: it trains women in self-doubt and self-limitation just as it exercises men's unsupported overconfidence.
Mansplaining is a condescending and unnecessary addition to a conversation, often consisting of explaining a point a woman already made or repeating it in slightly different words.
Mansplaining is beyond mere condescension and points to the privilege men have to assume that they are right, that women are wrong, and that their responsibility is to explain something to the poor woman who just can't understand it.
