besides the minor divinity question, i would think of the abortion/death penatly question to be of much more practical consequence.
as far as i am concerned people who approve of the death penalty are automatically heretics, but i am pretty sure most would think of abortion-"realists" like myself in a similar matter.
I would say that being a "realist" about abortion, as one would be about
e.g. foreign policy, would be on the leftward edge of orthodoxy but still within it, but thinking of abortion as a positive good would not be orthodox. ("Orthodoxy" defined in the broadest, most pan-Christian sense.)
