if the taxpayers don't pay for their birth control and eventually their abortions.
First of all, this woman appears to be fully capable of buying birth control for her daughters if that's her wish. She is also free to drive one or the other of the girls to an abortion clinic to have her grandchild sliced and diced when and if they are "punished" with a baby. She can even start a monthly budget entry for saving up for getting rid of inconvenient grandchildren.
What decent mother assumes that her daughters will, at the earliest age possible, rut like little feral animals? I remember when little girls dreamed of being mommies.
