When we talk with a prochoicer or with a prolifer what they show you is abortion or life, depending on the site. After four weeks of working for EMC I've seen that what prolife offers and what prochoice offers is more that just abortion or life.
Prochoice offers fear about a difficult future. Prochoice offers abortion because they are trying to sell to you that you cannot have hope of a better future with a baby. Proaborts want you to be desperate, because desesparation is the feeling that motivates you to kill your own children.
On the other hand prolifers offer aternative to their awful future. We don't think of a baby as a problem, so we try to help mothers with resources and also with hope.
