An utterly specious argument. Every law in existence there "legislates morals". The question is not, "Are we going to legislate morals?", but "Whose morals are we going to legislate?".
Ask yourself whose morals we're legislating by making Plan B OTC. Are they the morals you'd like for your own sons and daughters?

Look, it's a contraceptive product and it seems to beat the old coat hanger method.
(snip)3. How does Plan B work?
Plan B works like other birth control pills to prevent pregnancy. Plan B acts primarily by stopping the release of an egg from the ovary (ovulation). It may prevent the union of sperm and egg (fertilization). If fertilization does occur, Plan B may prevent a fertilized egg from attaching to the womb (implantation). If a fertilized egg is implanted prior to taking Plan B, Plan B will not work.

I don't depend upon governments to teach my family it's morals. We don't quite yet have a complete nanny state. Frankly I think the fed.s have their hands full trying to defend us from enemies - foreign and domestic.
