Proposed litmus test: infanticide.

General cultural norms label this practice as horrific, and most people's gut reactions concur. But a good chunk of rationality is separating emotions from logic. Once you've used atheism to eliminate a soul, and humans are "just" meat machines, and abortion is an ok if perhaps regrettable practice ... well, scientifically, there just isn't all that much difference between a fetus a couple months before birth, and an infant a couple of months after.

This doesn't argue that infants have zero value, but instead that they should be treated more like property or perhaps like pets (rather than like adult citizens). Don't unnecessarily cause them to suffer, but on the other hand you can choose to euthanize your own, if you wish, with no criminal consequences.

Get one of your friends who claims to be a rationalist. See if they can argue passionately in favor of infanticide.

Don't unnecessarily cause them to suffer,

Aren't abortions unnecessarily painful? This is as strong an argument pro-life as pro-infanticide.

I agree there a continuum between conception and being, say, 2 years old that is only superficially punctuated by the date of birth. Yet our cultural norms are not so inconsistent...

General cultural norms label [infanticide] as horrific, and most people's gut reactions concur.

For example, many of these same people would find it horrific to kill a late-stage fetus. And they might still find it horrific to murder a younger fetus, but nevertheless respect the mother's choice in the matter.
