Lawrence Lader was born in 1919 to Jewish parents. In his early adulthood he was a supporter of Marxism. He, along with Betty Friedan and Bernard Nathanson, was one of the founders of the pro-abortion group NARAL. Betty Friedan described him as "the founding father of the abortion movement".
Lader, Nathanson, and Friedan were all Jews, though in fairness to Dr Nathanson it must be pointed out that later in his life he broke with the proDeath movement, became an ardent ProLifer, and converted to Catholicism. By then, though, the damage had been done by he and his colleagues.
Abortion leader Nathanson wrote a good book on his transformation, so did the wild and hard, lesbian gal in Roe v Wade, when she became a pro-life Christian.
