Since self defense is a valid defense for a murder charge, murder itself is not against the constitution. In theory, the state legislature could pass legislation making “they looked at me funny” a valid defense for murder too if they wanted, so saying IVF makes murder okay should fly. I guess the state supreme court could say that this legislation runs afoul of the equal protection clause of the US Constitution since it only applies to some people, but who knows. Considering that these judges just make shit up these days they could strike it down because they passed it on a Wednesday.
