Radiocarbon (RC) or (C-14) dating of linen, cotton, bones, fossils, wood, sea shells, seeds, coal, diamond (anything with carbon) is one of the most common and well understood of the various scientific dating methods.
This is completely and utterly untrue. For example, you can't use carbon dating to date diamonds at all; the simple reason being that carbon dating can only work on the remains of organisms. Organisms that could breath. I've never seen a breathing diamond.
Carbon dating certainly won't work on 'anything with carbon', at all.
Thus, just reading the first sentence from your source, I came to the following conclusions about the authors of the source you provided: 1. The authors of your source deliberately lied to you, and/or 2. The authors of your source are clowns who pretend that they know something about carbon dating, and/or 3. The authors of your source material are creationists.
Without reading the rest, I can predict that the authors of your source material do and are all of the above.
