Yes, well stated - it amazes me how many people don't know how EC works (Despite the most common form of EC being heavy doses of your standard oral contraceptives. Hmm, we've figured out how those work and other than those who feel no artificial means of contraception should be used EVER, no body is screaming abortifacient about OCs.)

Now, a copper IUD as an emergency contraceptive does open a different moral can of worms. It does prevent implantation (in most cases - they're also not 100% effective) if fertilization has already occured.

And somewhat related, what really pisses me off about many anti-abortionists is that they are under the misperception that most abortions are partial-birth/late-stage that involve near-birth size fetuses. Most abortions happen in the early weeks of pregnancy when the embryonic tissues are fairly indistinguishable from the uterine lining - see Visembryo for a good visual of the actual size of the embryo at the early stages of pregnancy. (I will warn that viewing these pages and the processes of pre-natal development may change attitudes toward abortion - no, nothing is gross, it's just pretty amazing how quickly human features are developed.)
