I'll respond to the above points in a few hours. I just wanted to post this.

A while ago there was a Personhood amendment in Mississippi which would've defined human life starting at the moment of conception. In the case of rape, incest, stroke, ectopic pregnancy, and possible death to the mother it would be illegal to abort the fetus. Furthermore if a miscarriage were to occur it would have to be investigated as a homicide. Treatments that could help the mother, but hurt the fetus, would've been illegal. Thankfully it was rejected, but you see the kind of slippery slope that was almost crossed in the name of "pro-life" right? That could've become law in a state.

Imagine you & your girlfriend are saddened by a miscarriage. You were both pro-life and were excited for the kid. Cops come into your house to investigate things, find some day after pills left over from your girlfriend's sister when it was legal to have those. Suddenly your girlfriend is in prison for murder even though you were both pro-life. If that "Personhood amendment" became a law something like that could've happened.
