Pro-choicers need to stop acting like pregnancy and the cause is unknown, like some type of cancer diagnosis. Most, every mentally capable adult knows how pregnancy happens. And yes, not having sex is a way NOT to get pregnant. Ample amounts of birth control exist. There are ways to enjoy sex outside of intercourse. Hell a lot of woman may prefer oral stimulation over penetrative. My point, we all know the potential result of sex. It's not a surprise. There are many ways to avoid pregnancy while still enjoying "sex".
And I will put the a lot of the responsibility on men, who probably do pressure woman into unprotected sex and then when a pregnancy occurs, pressure the woman into an abortion.
Many choices could have been made that can avoid pregnancy. There are two equally culpable parties when sex occurs. Guys and gals, if there is not birth control present, don't stick it in. Find another hole, or use hands, or do something else.
