This is where we go back to elementary school and put on our thinking caps. How is an abortion which is an individual decision compared to as you stated, "..... slaughter of another group of people?" Come one dude.
That is a right wing talking point that doesn't factor the many senarios that go in the decision. The truth is there are people who think their ideology is more important than other people well being. The states outlawing abortion right now are not putting more money into foster homes and welfare programs.
