I haven't read all the posts here so if this has already been covered I apologise.
I am no longer against early abortion, e.g. a 3-day old human embryo consists of 150 cells called a blastocyst. Such embryos could help countless millions of sick people through stem cell research. When such embryos are destroyed for stem cell research they do not have any formed brains or neurons so there is no reason to assume that they feel pain. Stem cell research could offer potential cures for most diseases or injuries that people suffer, including cancer. To put it into context, there are more than 100,000 cells in the brain of a fly, so killing a fly could be said to be causing far more suffering than destroying a blastocyst.
Many people say, as I used to, that conception begins once the sperm fertilizes the egg and, therefore, life has started. The truth is, as shown above, that in the early stages there are no neurons so there is no pain to be felt. The problem is that abortion is such an emotive subject, with anti-abortionists saying even a blastocyst is life and to take such is murder. But what about the fly?
I can fully agree with anyone who is against the termination of a fully formed fetus, but I don't believe any woman who undertakes to have a termination does so lightly. Only the woman (and possibly her husband/partner) knows why they feel they must go through with it and it is not for us to judge and to have that poor soul carry the label of "murderer" on their shoulders for the rest of their lives. They go through enough angst as it is!
So, in answer to your question, yes, I have changed my mind.
