Because being pregnant is actually pretty dangerous for women. It can be especially dangerous if you're in your mid-30's or older. And it's also really dangerous if you're not planning to become pregnant because babies remove essential nutrients from your body. Don't get me started on the risk of eclampsia, gestational diabetes, and post-partum depression. Babies also modify your immune system and may make you more susceptible to diseases. Delivery can be very risky too depending on the shape of your body, and some women have to undergo physically altering surgeries to deliver. Miscarriages can also kill women by causing them to bleed to death really quickly.

I think it's important to allow women to make decisions about pregnancy based on their perceived risk, rather than blithely dismissing the morning after pill as being akin to steroids.
