As a moral issue, I say look at the old testament and see exactly what the penalty is for causing a miscarriage.  It isn't death... it was monetary.  If you killed the mother though, that was death.  The value was placed on the person who was born, not the unborn child.  So if we are using the bible as a moral barometer, lets have some perspective.  

I believe it is in Leveticus, which they cite as condemning homosexuality... these hypocrites need to take it all literally or not at all... they should not pick and choose to fit their agenda.
