A spanking is a punishment. There is a difference between a spanking and a beating. A beating is always wrong and anyone does this should be put in jail. A spanking also should never be the first punishment but the last and only in serious situations.
Abortion or no abortion is a HUGE deal. Spanking or not spanking ... not as much. But as my2cents said, when a spanking is a beating ... that's a HUGE deal.
