It’s not just gay marriage on which the mostly Catholic states are on the wrong side of God’s Law, relative to mostly Protestant states. It’s a whole array of social pathologies, including divorce (the mostly Catholic states even have higher divorce rates than the mostly Protestant states).
Also, even though the Catholic Church CLAIMS to oppose abortion, the mostly Catholic states (like New York) have abortion rates 6-10 TIMES higher than mostly Protestant states like South Dakota (43.3 vs 5.7 abortions per 1,000 women between 15 to 44 years old).
They even have much higher murder rates (6 murders per 100,000 population compared to only 0.2 in North Dakota).
This sure does not seem to be very smart on their part, wouldn’t you say?
