@JohnLawler: That analogy is unreasonable. The debate around evolution is not merely about terminology and definitions, but about whether or not something actually happened in the past. Using one of the various acceptable definitions of the word "tense" is fine, and the one you are on a crusade against happens to be the one that is most widely used. Linguists use many different definitions. Why do you care so much about the definition of a word? You're battling windmills. — Cerberus 10 secs ago
