Definition of HETEROPHOBIA

: irrational fear of, aversion to, or discrimination against heterosexual people

As in so many areas of our society, divisions are drawn in black and white; there are no shades of gray. Homophobia is countered by heterophobia; the empty answer to gay-bashing is a vow to bash back. There are sadder developments in American life, I suppose, but for the moment, I can't think of one.Pete Hamill, Esquire, August 1990
