Limiting one group to protect another group is exactly how anti-gay lobbyists justified being anti-gay-marriage.
The difference between those situations is that with regard to those utilizing that argument in an anti-gay-marriage movement, they were demonstrably wrong. On the other hand there is no doubt that excessive alcohol consumption damages babies.
Forgetting issues of enforcability, what do you consider the moral difference between punishing a mother of a baby whose drinking resulted in physical harm to that baby and doing the same to a woman whose viable child was still in-utero?
