All Catholics are pro-life, many pro-life activists who are not Catholic convert as they are exposed to that reality. (If they are pro-abortion, they are NOT Catholic. Period. No matter what they claim.)
In my practice I have many RCs on oral contraceptives. So based on your statement there are maybe 323 RCs in the US?
IMO you can't claim that and simulateously claim that the Catholic Church is the largest Christian body in the USA. Take your pick.
Seriously, Isn't there such a thing as a BAD Catholic or an excommunicated Catholic (or even a treacherous Catholic)?
