Are those who are strongly opposed to abortion ready to deal with the consequences of society if such a thing would be outlawed? Welfare, and poor families have their 8th kid, a impregnated 4th grader who was molested by her father, your wife becoming pregnant after being raped, etc?
Do you have any idea how many couples are looking to adopt? The rate is astronmical. The liklihood of getting to adopt is dropping substatntially. If there were more births, there would still be people looking to adopt those babies. Remember, adoption is a much better avenue than terminating a life. It is not the child's fault that it was conceived, so why blame him/her by killing them?
