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.
I was using the example of an unmarried woman who has sex twice a week for a year to demonstrate a statistical likelihood of pregnancy. I suppose there are lots of ways to describe such a person. I used the term that I thought appropriate.
Sorry, I was just trying to put it in someone else’s terms (which I tried to make clear that those were their words, not mine) to try to make it easier for them to understand my point of view... at least, that was the general intention.
