There are many more sluts than playboys.
And women have many ways of satisfying the badboy they are *ahem* "dating" (that week, or the last-six-weeks) which will not result in either abortion (an abomination before God) or in children with pathologies and a vast increase in social spending.
The real question is, why aren't other WOMEN slut-shaming as they used to?
But I think you already know the answer to that.
The reason so many of who you call ‘sluts’ get abortions is because of your shaming of the women and not shaming the men.
