Why not? When i was an agnostic I liked the Catholic church as an institution (and many other religious organisations too).
> The idea is that by relaxing norms, he wants to gain more members.
That is a ridiculously cynical take. People join the church, and even more the priesthood because they believe. Why would they corrupt the message to get the numbers up?
I do not know what norms have been relaxed by the church anyway? Changing the mass used by the majority of Catholics? Its happened many times historically.
> But it doesn't actually go that way. It alienates the core, and the people for whom compromises are made don't want to join anyway.
I see no sign of alienation except in small fringe groups (so not the "core").
> You can see this with the number of members for Unitarian churches (declining) vs Amish (growing).
The Catholic church is growing globally.
