Uh, yes it does. If they are Pro-Choice, they are not Catholic.
Let me make this simple for you, in the Catholic faith, life begins at conception, there is no pro-choice stand as a Catholic, to claim to be Pro-Choice as a catholic is to be Pro-Murder, period.
If you believe this you are not Catholic, you can sit in the pew every sunday all you want, but you are not a practicing Catholic, no matter how much you dillude yourself to the contrary.
Considering oneself Catholic does not make one Catholic.. I can “consider” myself African-American, but that does not make it so. Your “catholic” friends that are pro-choice, are living completely at odds with the Catholic faith, so by very definition they are not Cathlic, no matter what they “consider” themselves.
As I said, I am not Catholic. You write as though you are. So you certainly know more about this than I.
