There is more to voting than just the WOT. I notice from your earlier post that you don't believe laws should be enacted to prohibit the murder of unborn children, so perhaps we're just at a different place with regard to how dear we hold our principles.
I am very opposed to abortion and I try to help people arrive at a decision to carry their babies to term. Calling abortion "murder" actually makes my arguments against abortion less effective and therefore leads to an increase in the number of abortions.
