Ex Mormon subreddit participants self select for those who have ex mormom experiences worth discussing.

154k subscribers on a base of 15M --> ~1% that make it through the filters of being able to go online, find reddit, and find enough interest to subscribe. That suggests the experience is common enough to not be disregarded.

That’s because most Catholics never go to church anyway. But they certainly do care if you don’t baptize their grandchildren.

They do, but it's also not uncommon for Catholics to violate any other precept, e.g. divorce. It's a very lax culture, in this age, in the developed world.

I have plenty of Catholic friends who decided not to baptize their children, grandparents weren't happy but it's rarely a reason to truncate relationships.

Edit: anecdotal evidence, of course, YMMV.

I don't go to Mass, but there was no question we were going to baptize the kids. In part, that's because the Catholic youth sacraments happen on a pretty well-defined schedule and it's weird (socially) to get them done off that schedule, so baptizing (and First Communion, which both of my kids also did) preserves optionality.

Mormon's that don't go to church for months at a time are not considered active mormons. I don't know if that's the case for catholics or many religions where much of the focus is on a pastor/bishop giving a sermon. In mormon church's each attendee is called on to do something: give a sermon, teach a class, visit a family, clean the building, etc. There are a lot of things to do. I'd assume that for any organized religion that had the same expectations of it's participants, severing from said religion would be a greater life change than those who just observe.
