Misandry is the hatred of men. It is a combination of two Greek words namely miso, which means hatred, and andros, meaning man or male human.[2] A neologism formed analogous to misogyny (hatred or contempt for women), it was first used widely in the 1970s in response to perceived hatreds within the feminist movement.
Today, the term is frequently misused by men's rights activists (MRAs), who use it to refer to anything even vaguely resembling feminism, and/or any time a woman hurts their feelings.[note 2] As an imaginary structural bias in society as a whole, invented to counter accusations of misogyny, it is essentially identical to "reverse sexism", and analogous to reverse racism and other forms of reverse discrimination, which certainly do exist but only on an individual or otherwise subordinate level in society.
When focusing more on "institutionalized" (in other words, actually malignant) hatreds, the term is not used that much, as unlike women, who are usually somewhat underprivileged in most societies, men are not actually denied their rights and freedoms. Thus, some may suspect that the existence and/or relevance of the word itself, some even attributing its existence to an alleged conspiracy of male dictionary editors. It may help that they are themselves often accused of being misandrists, although to be fair, simply failing to acknowledge the existence of a privileged person’s hurt feelings is not actual sexism
