The point which needs to be re-emphasized more clearly is that many of the causes of conservatism these days are utterly contradictory to a pro-life position. You cannot say that you are pro-life, but that you think people should have the right to choose if they want to kill themselves with cholesterol. After all, these same people say that euthanasia should be illegal, yet it should be OK to kill yourself with hamburgers, alcohol, cigarettes, and the CHOICE to not wear your seatbelt, among other right-wing crusades de jour. We all have moments of inconsistency, but it would do the disarrayed right-wing some good to think about the fundamental contradictions in their professed pro-life position. Are they really pro-life when they support the rights of polluters to put toxins into our air and water? Are they really pro-life when they want to weaken or eliminate worker safety standards that may lead to more people dying on the job? Who is really more pro-life when their opponents are the ones who want health care for all, and they adopt the pro-choice position that people should choose whether they want to purchase health care coverage at all?
If life really is a right, as the so-called right-to-life movement professes in three word bumper sticker prose, then a right is not an option or something that others can choose not to recognize. If they really want others to take their "pro-life" rhetoric more seriously then they have not try to use abortion as an excuse to abort health care for millions of Americans, as they attempted to do with congressman Stupak. If they really want to promote life then they need to be in favor of public safety relating to the regulation of speeding, and the use of safety equipment, instead of claiming their freedom to choose not to abide by those standards, even when the exercise of that "freedom" ends up endangering or injuring other people.
In the end, I don't see Republicans making much effort to be pro-life, but just using it as an empty, self-righteous gimmick for preaching (literally) and fundraising. Few of them really believe in doing things that protect or respect life when they make the lives of gay people hellish, and rail against immigrants who come to the US in search of a better life. It is hard to believe that people with so much hatred for the living can be "pro-life". Right-wingers may take some of this to heart, turn over a new leaf, and prove me wrong some day, but I am too "pro-life" to hold my breath waiting for that.
