The Roman church, which used to ruthlessly ferret out what it called anti-Christian heresy, has in recent years taken to making kissy-poo towards any religion, the idea seeming to be that it might be a staging point for eventual belief in Catholicism.
This has gone on long enough that some kind of empirical test should be possible — has the attitude shift succeeded in welcoming more former Muslims into the Roman church?
I took a lot of their kissy poo stuff things done or said to protect medical missionaries in areas with Moslems present.
