For example, among the "prolife" side, there is one strand of argument that opposes abortion rights from a "cultural" perspective. They see the ability of women to have sex without "facing the consequences" as an attack on "traditional" society, and oppose abortion rights and contraceptive education with near equal vigor.
My view is similar to this, but a bit expanded. While yes, "responsibility of your actions" has to be taken into consideration, the burden should not rest upon the mother alone. The man who impregnates the woman has just as much responsibility for the child. If the couple is not married, and has no intention to become married, he must provide child support to the mother until the child turns 18 or the child is placed up for addoption. With the mother being the one who brought the child into the world, it would be her decision to place the child up for adoption, not the fathers.
But in either case, the decision to have sex is theirs alone. If the woman is not a willing participant (rape, incest,....), abortion should be allowed. Just as if her life is in danger due to the pregnancy.
