I've never heard a compelling point in favor of the idea that we ought to treat each fetus as a member of society, even in a limited sense.
That said, I would tolerate a fairly strict set of restrictions - a ban after the first trimester, say, which comprises the lion's share of abortions anyway - with comparatively little complaint if it meant diminishing how heavily the issue figures in our politics. The public debate is absolutely noxious, futile, and ridiculous. None of us profits from claiming that our opponents are irredeemable sexists or abettors of mass murder, and I doubt that most of those who make these claims actually believe them.
On the contrary, I think at least half the pro-choicers here legitimately believe that people who are against abortions are irredeemable misogynists. It really makes me lose a ton of respect for those folks, too. Cuz they're really missing the point.
