Okay. So your "test" is viability outside the womb. And you recognize the principle that since it's impossible to delineate a bright line where a fetus is "alive", it's prudent to prohibit abortions after a much earlier time.
Now my "test" happens to be whether the fetus has the potential to become a child. And I don't purport to know when life begins, so I tend to be more cautious. I don't support abortions, period.
Does that make me a member of the religious right? Would I be disqualified from receiving your vote based on this issue alone?
If you said that you would make it a centerpiece of your political life to impose your beliefs on me, yes. I would disqualify you.
If you said that you believed as you do but acknowledged that not everyone believes as you do and that no one has an indisputable answer, no. I would not disqualify you.
