I agree. It is a typical knee jerk reaction. Some say it prevents implantation, others say it prevents fertilization. Huge difference. Knowing the facts would be helpful. As a nurse, this is how I have undertsood the drug works; by preventing fertilization in the first place. Not that different than spermacides, etc. Of course some people are opposed to all birth control measures so to them ,then, well...it would be irrelevant.I agree with you too. And yes, facts would be helpful, but I've found that facts are usually ineffective arguments when one is arguing with brick walls. ;)
