Women do not view children as throw away items, but some women, for a variety of reasons, cannot look after a child, (and all that entails, for 18-20 years), these reasons can be lack of stable environment, a lack of finances, conception as a result of rape or incest, ill health, and a number of other reasons.
If all women were forced to give birth, there would be a lot of unwanted children to look after. My question is who is going to do this?
