But I don't think you're going to convince him. The Dawkins link couldn't convince him.
Hundreds of posts ago, various Freepers were talking about getting agreement on our terms. Since then, we've been through observer, evolution, value. It is baffling to me when one word is used in a technical sense yet another in a common sense.
At any rate, failure to agree on the words - or redefining terms in midstream - can't be helpful. Common usage is probably the most important because a lot of Lurkers come by and read a few posts, then leave. Without a parenthetical definition, they could get the wrong impression of what was being said.
