Dirius, it's time to stop pretending to be so clueless.
As I pointed out in my initial post on the previous page, many unwanted pregnancies are the result of failed birth control. Look up the failure rate of condoms. I think it's around 10%. Condoms can slip off inside the woman's vagina, notably after a man ejaculates and his penis reverts to its smaller flacid size, and such condoms don't necessarily contain all of the semen.
Some men don't feel sufficently relaxed about having to put on a condom to use them, perhaps relying on early withdrawal. You can imagine the pregnancy rate with that method. Ditto for the rhythm method.
Birth control pills should not be taken during a woman's entire fertile period for health reasons. Cervical caps, diaphragms, and other mechanical barriers have the same problem of slippage. IUDs today are the most effective, but the early ones had real health problems, so many women today still prefer to steer clear of them.
Give me a major break. Look up ectopic pregnancy, pre-eclampsia, and incompatible blood types. What about women who must be on medication for their own health and even survival, when that medication would harm a fetus? Think of cancer treatments and anti-psychotic drugs. Would you personally want to carry a fetus to term, knowing its severe birth defects would make it unable to live more than a few hours? Would you personally want to carry the fetus of your rapist-- or father?
Do you know how many girls have been beaten or thrown out of the house when they informed their parent they were pregnant? (A real problem with deeply "religious" families.)
You are not a father. You have not been close to a pregnant spouse or partner, to see the sorts of health issues many pregnant women and some children endure.
What about raising the child, from birth through age 18 or so? What if you were indeed married-- but very poor and didn't see how you and your husband could afford baby #5.
You're the one with the all the convenience, Dirius.
