Do the moral issues involved in abortion and gay marriage...

Abortion Was Legal

Abortion has been performed for thousands of years, and in every society that has been studied. It was legal in the United States from the time the earliest settlers arrived. At the time the Constitution was adopted, abortions before "quickening" were openly advertised and commonly performed.

Making Abortion Illegal
In the mid-to-late 1800s states began passing laws that made abortion illegal. The motivations for anti-abortion laws varied from state to state. One of the reasons included fears that the population would be dominated by the children of newly arriving immigrants, whose birth rates were higher than those of "native" Anglo-Saxon women.

The Medical Establishment
The strongest force behind the drive to criminalize abortion was the attempt by doctors to establish for themselves exclusive rights to practice medicine. They wanted to prevent "untrained" practitioners, including midwives, apothecaries, and homeopaths, from competing with them for patients and for patient fees.

Liberalization of Abortion Laws

Between 1967 and 1973 one-third of the states liberalized or repealed their criminal abortion laws. However, the right to have an abortion in all states was only made available to American women in 1973 when the Supreme Court struck down the remaining restrictive state laws with its ruling in Roe v. Wade.
