I personally find the slippery slope both A) an ever-encroaching reality, and B) horrifying.
Well there's two slippery slopes. The "abortion is the lynchpin in the culture of death (abortion, euthanasia, human embryonic stem cells research, prenatal screening, organ harvesting)" slippery slope and then the "any restrictions on abortion now will eventually return women to the back-alley for abortions" slippery slope.
Speaking as a medical professional rather than a conservative, I think present and future advances in hi-tech medicine, fetal surgeries, embryology and biological research will, at the least, cause society and individuals to; gain different perspectives, rethink their views, and examine their consciences regarding the legal status of fetuses.
We've already seen this trend, for example, with fetal homicide laws, the sharp decline in the number of medical students training to perform abortions, and the public rebuking of pregnant women who smoke or consume alcohol.
As a conservative, I hope this is the direction society heads because, I too, am horrified (and have read enough science fiction
) to see where medical technology could take us otherwise.
