Actually much of what they got was from the Protestant Margaret Sanger, the racist founder of Planned Parenthood.
In fact she opposed mostly Protestant law makers who enacted the Comstock Law:
In the 1910's and 1920's, the entire social order–religion, law, politics, medicine, and the media–was arrayed against the idea and practice of birth control. This opposition began in 1873 when an overwhelmingly Protestant Congress passed, and a Protestant president signed into law, a bill that became known as the Comstock Law, named after its main proponent, Anthony Comstock. The U.S. Congress classified obscene writing, along with drugs, and devices and articles that prevented conception or caused abortion, under the same net of criminality and forbade their importation or mailing.
Sanger set out to have such legislation abolished or amended. Her initial efforts were directed at the Congress with the opening of a Washington, D.C., office of her American Birth Control League in 1926. Sanger wanted to amend section 211 of the U.S. criminal code to allow the interstate shipment and mailing of contraceptives among physicians, druggists and drug manufacturers.

Sanger had many 'issues' in her childhood. To pin her as a "Protestant" is absurd as she was clearly into the shadowy eugenics movement.
Perhaps the genetic BS, but the actions taken against the Jews were well practiced by the Catholic church.
