This association of the Abortion Act of 1967 with "murder", "eugenics" and "the left" is so ridiculous and small-minded it is worth highlighting what the position was prior to the Abortion Act being passed.
Between 1861 and 1929 if a woman attempted to have an abortion by poison or any other means, and anyone who assisted her, would be liable to prosecution with a penalty of between two years and life imprisonment under the Offences Against the Person Act.
In 1929 the Infant Life (Preservation) Act allowed abortion only if it was done to preserve the life of the mother.
Then in 1967 the Abortion Act was passed which also allowed abortion for other reasons including the probability that the child would be seriously handicapped, either mentally or physically, when born.
Prior to this a woman who had been raped (and became pregnant), or was a victim of incest (and became pregnant), or who believed her unborn child would be seriously handicapped ... and did not want the child ... would get an illegal abortion with all the medical risks that went with that. A National Poll at the time of the 1967 Abortion Act estimated that there were 31,000 illegal abortions a year, and a total of 600,000 abortions from 1946-66, mostly illegal.
Which was the better scenario when a pregnant woman was determined to get an abortion? That it be performed in a hospital by a qualified doctor, or in some backstreet under cover of darkness which often resulted in infection or worse.
