Pregnant but not married

define who this 'we' is that you are talking about, if the 'we' is US society in general then..

we are against teen pregenancies because teenagers are not ready or able to fufill parental responsibilities

a 30 year old is on the other hand is able.

well depends on the person there are married couples with kids who should have been neutered instead of allowing to hve kids, I am talking about abusers, baby killers etc..

but in general a 30 year old having a kid is very diff than a 16 year old having a kid..
