We need more fetuses for stem cell research, all of them should be aborted for like 3 years, no more infants for 3 years.
Aside from the civil rights implications, I don't think this is a terrible idea. Not to enforce abortions (kinda legally indefensible), but to use them all for stem cell research.
I don't think you'd need to mandate them for it to be an effective policy, they're super common.
