From ChurchMilitant.com we have an excellent program today detailing how contraception and abortion are inextricably intertwined. In the first few minutes, they briefly skim over the history of contraception just prior to that dismal 1930 Lambeth Conference. For a more in depth treatise of contraception and eugenics in the United States, I'd suggest watching Maafa 21. I'll post that video below the Church Militant one.
Around the 14:00 mark, Christine Niles states what should be an obvious point: that without contraception there would be no abortion, yet pro-lifers won't discuss it. Indeed, many pro-lifers actually support contraception, a completely nonsensical stance. The usage of contraception stems from the same anti-life mentality as does abortion. My blogging colleague at Les Femmes asks why we don't march on June 7, the anniversary of the Griswold v Connecticut ruling that unleashed contraception on America. That's a good question. We should also ask why the bishops will not allow their priests to preach on its evils.
