People fuck for various reasons. Taking away people’s access to contraception doesn’t stop that, it merely makes it more likely they’ll have kids.

Abstinence only programs have shown themselves again and again to just produce teen pregnancies and STDs. Contraception, generally, is the best way to keep yourself from producing a child and the people who are against it tend to be the type of people who want the state to get into your bedroom.

Which is why republicans and conservatives want it gone: they want you to have children.
