Unless the mother’s life is in jeopardy, abortion is murder with one of the cruelest and most selfish of motives....convenience. Can’t find a right to “convenience killings” in the 1st amendment.
If you believe aborting a child is murder and it’s done because the mother’s life is in danger, it’s still murder.
Personality I think any exemption shows a lack of true belief. Either abortion is murder or it isn’t.
