You get the idea
Alright, so your idea is to implement a totalitarian state so you can ban contraception.
We already had many totalitarian states. They didnt ever reduce teen pregnancy. However, the access to contraception has reduced teen pregnancy by 40%.
So on the simple question of what is a better solution to teen pregnancy: a totalitarian state or simply access to contraception, I am going to vote for access to contraception.
