For example, there is no point in excommunicating "Catholics for Choice" or whatever group it is that goes around calling themselves Catholic as they seek to encourage abortion.
Anyone who procures or helps another to procure an abortion (by paving the way of ideological pressure and coercion), obtains a latae sententiae excommunication.
It's like beating a dead horse.
And do you know what ELSE is like beating a dead horse? Trying to teach anti-Catholic smear artists like Viva and faith_j the truth about the Catholic Church. They don't know because they don't want to know. Why would they want to interrupt a really good hate?
