[Tea Party Terrorist]

Things have a gender. People have a sex. There are only 2 sexes.

Take back the language.

[Dr. Sivana]

From Fowler's "Modern English Usage" edited by Sir Ernest Gowers (Oxford, second edition, 1965):

"Gender, n., is a grammatical term only. To talk of 'persons' or 'creatures of the masculine or feminine gender,' meaning 'of the male or female sex,' is either a jocularity (permissible or not according to context) or a blunder."
