Misandry is strong dislike of all men. If your dog barks ferociously at every single man she encounters, you may wonder if she suffers from misandry.
You're probably more familiar with the word misogyny, "hatred of women." However, misandry is also a prejudice based simply on a person's sex, and just like racism and other forms of bigotry, it's unfair. A boss's refusal to promote men may stem from misandry — or it may be because the women who work for her happen to be more highly qualified.
