From Still the Best Hope: Why the World Needs American Values to Triumph by Dennis Prager:
The Left, as repeatedly shown here, wishes to control as much of people’s lives as possible. There are, however, two noteworthy exceptions — abortion and sex. In these two areas of human conduct the Left wants people to be left alone.
With regard to abortion, the Leftist view is that the human fetus has no rights at any point in its development. The mother has complete freedom to destroy it at any time for any reason. Not only does the Left oppose any legal bans on abortion, but pro-choice activists will not even morally condemn any abortion. If an affluent and married woman wishes to abort because she does not want another child, that is not morally wrong. If a woman wishes to abort one fetus of two she is carrying because she wants only one more child, that is not morally wrong. If a woman wants a boy and aborts a female fetus, that is not morally wrong.
For the Left, aborting human fetuses at any time for any reason is an absolute right over which society should have no authority. On the other hand, in almost every other area of life, as documented above, the Left seeks more and more governmental authority over the individual.
