Francis Deblauwe has done a statistical analysis of the division among Catholics on the 'social sins' at his website Word Face-Off. Here is what he has to say:
Denver Roman Catholic Archbishop Charles Chaput recently shattered the wall supposedly separating Church and State in the US ("Obama the 'most committed' abortion-rights major-party presidential candidate since the landmark Roe v. Wade decision on abortion in 1973.").
He was of course not the first prelate to do so, his companions were among others former St. Louis, now Vatican Archbishop Raymond L. Burke (Democratic Party = "party of death"), St. Louis Bishop Robert J. Herman (coming election = "Judgement Day"), Dallas Bishop Kevin Farrell and Fort Worth Bishop Kevin Vann ("The reading of the letter during Mass on Sunday at Holy Trinity Church in downtown Dallas prompted about two dozen parishioners to walk out."), etc.
Progressive Catholics are pushing back against these prelates' myopic obsession with abortion, e.g., Lisa Sowle Cahill (Professor of Theology at Boston College), Douglas Kmiec (Professor of Constitutional Law at Pepperdine University, former head of the Office of Legal Counsel for Presidents Ronald Reagan and George H.W. Bush), Cathleen Kaveny (Professor of Law and Theology at the University of Notre Dame), Nicholas P. Cafardi (former dean of the Duquesne University School of Law in Pittsburgh; recently de facto forced to resign as trustee of Franciscan University of Steubenville in Ohio), etc.
In light of all this, I thought it useful to face off the attention some of the most commonly cited "social sins" had been getting from Googlers.
I widened the search to include the "against ..." phrases so as to try to account for all the Google-popularity. Worldwide, anti-war was very dominant, even more so in the early years when the Iraq War was still more in the news. Anti-abortion was a steady second and just this month overtook anti-war.
