You appear to speak for all Christians, Many of whom do not believe in absolutes, in fact I would say from my own experience, that you are a rare Christian if you do believe in absolutes. I believe you are wrong when you do not include science in you list of absolutes for science based on revealed truth received by man from the source of all truth must be considered true and worthwhile.
I beleive your personal opinion tells you that abortion is murder. The scriptures certainly do not, and I believe that Christians calling those who support the so called "womens health" movement, and "choice" after conception, are guilty of emboldening those who are already on the path to destruction, and you leave them no out, and therefor the empasse between the two sides of the argument. I have already stated my believe that neither side is dealing with a full deck, and my point is not to justify either side. Abortion is wrong, but the actions of Christians vis-a-vis those with the wrong ideas, are not helping the situation, and both remain unbending, and unable to listen to other ideas or possible solutions.
It's the same as the War on drugs, and the situation that will bring no solutions, ie don't confuse me with the facts, my mind is made up, and thus cutting off all dialog, and what remains is not good for anyone, especially the million or so aborted in this country alone every year, if that is a valid statistic.
