If atheists "follow the science"....

If atheists "follow the science" then all of them should be anti-abortionists because "Biologists from 1,058 academic institutions around the world assessed survey items on when a human's life begins and, overall, 96%{5337in out of 5577} affirmed the fertilization view" [1] and unjustly killing an innocent human is murder. But 87 percent of atheists support abortion.[2] Curious...

Perhaps there is some scientific data that challenges the life begins at conception view.

Perhaps there is an exception to the killing of the unborn that makes it okay.

That would be their argument to make.

Or perhaps atheists only "follow the science" when it's convenient for them
