The question was...
Are The Democrats Wanton Baby-Killers?
The answer is no for two reasons.
First: Not all Democrats are Pro-Choice. Being a Democrat doesn't mean that you agree to everything in the platform. Some Pro-Life Democrats have been a burr in the saddle for Pro-Choice Democrats. One of the most proactive Pro-Life groups in the U.S. is the DFLA (Democrats for Life of America).
Second: While the prevailing opinion among Democrats is Pro-Choice in it's politics, Democrats do not FORCE anyone to have an abortion. If every woman in America decided not to procure abortions, abortion would not be taking place. The wanton "baby-killers" are those women who procure abortion after abortion as though it is some easy birth control fix.
Democrats simply believe that women should have a choice with regards to the issue for various reasons. As do most Libertarians. However, there are even Pro-Life Libertarians.
Surprisingly most Democrats are not against measures that stand to reduce the abortion rate. What many don't know is that most social initiatives aimed at reducing the abortion rate are Democratic initiatives. Pro-Life Republicans have primarily focused on merely banning abortion.
