Becasue kids with downs syndrom take more care, which means that promiscuous mothers aren’t as free to go out and sleep aroudn any longer- it’s cramping hteir style- They want to be free fro mthe extra responsibilities so hey can keep up the promiscous lifestyles they had before they ‘accidently became pregnant’
I’d agree with you only that most mothers in these cases are in fact married and are not “sleeping around”. Usually it is the whole family that decides the abortion is necessary. Mother, father, grandparents et cetera.
