Well let's see, 99% effective (if you accept that number, but let's just give them that) means 1 time in a 100 it FAILS. Now if a conservative slut has sex once a week that means she's guaranteed to get pregnant within two years. Twice a week of course means getting pregnant once a year.
That 70% is 70% of women seeking abortions, not all women. So 70% are promiscuous, and 30% are something else.
It makes sense to me.
Just curious but where in the article does it say they are sluts? Or is this your learned opinion? The sister in law of a good friend was married, had the two kids she wanted and used abortion for birth control. Was she a slut? Nope, just a murderess.
A co-worker was told after her IVF baby that she could not pregnant because of a preexisting condition. She was on the pill and got pregnant. She kept the baby and then had her tubes tied.
