There are two main reasons to abolish the apartheid of sex: it's unfair and it's unjust. It's unfair because it denies each of us the ability to express our personality in the only life we have, locking ourselves up in a prison of gender that we never asked for and never chose. It's unjust because, as Martin Luther King taught, it is wrong to treat people differently simply because of biology over which they have no control, and which makes no difference in day-to-day life. How about equal rights for men and women? Great, we need it, but King also taught us that separate is never equal, as the age-old mutilation of women's bodies, minds and lives amply demonstrates.
