I likely don't agree with you on the morality aspect of it, but, that aside...
From a legal perspective, it seems rather contradictory. We will not give you birth control as an over the counter option, and thus you have to obtain that with a doctor's prescription, but we will gladly give you the Morning After Pill over the counter, despite the fact that it's only a higher dose of the birth control pills that we won't let you obtain OTC.
With such fucked up laws that shouldn't co-existent, it's a wonder why so many people are pissed at politicians.
