how does being Catholic make being ABDL off limits? there are lots of christian ABDLs, there's nothing in any version of the bible that states that wearing diapers or enjoying childish things are a sin or bad. those two things are completely unrelated
There's a whole host of things, and they're not from the bible. I grew up attending a Catholic Church, which has its own set of doctrines and dogmas that it forces on its congregation, and they're not explicitly outlined in the bible. Take the concept of Purgatory, a realm of the afterlife between heaven and hell where people go for a certain amount of time depending on their sins, before being sent to heaven. When people die their family must pray for them so that they can go to purgatory, otherwise they go to hell. There is no mention of it in the bible, with only a few apocryphal chapters eluding to anything of the sort, but it's part of Catholic doctrine.
As for what does, it's teachings about the sanctity of children, how a man must provide for his household, how diapers could be seen as a form of idolatry, how masturbation, pornography, and sex outside of marriage are strictly forbidden (and since this began as a sexual thing for me I can never separate the two), and lots more. If the Pope were to be informed about ABDL, he would almost certainly condemn it as a moral evil.
I'm not Catholic anymore, I'm not even religious, but my parents are Anglican and yet my brain struggles to accept the fact that something forbidden by one denomination could be okay in the eyes of another. I just can't do it. Every single time I did anything ABDL related I imagined my grandparents looking down on me and what I was doing (a major Catholic teaching aimed to force confessions and donations) and I just couldn't bear it.
While there are a lot of Christian ABDLs, there are probably not many Catholic ABDLs, and even less (ex-)Evangelical Catholics. I spent a lot of my childhood spreading Catholic doctrine so it really can't ever leave me. It will be part of me forever, but I can try to get rid of this. I also know a couple of Christian ABDLs who have said that they struggle to rationalise it in their head every day, and my history as an evangelical makes this even more difficult. I doubt that there are many devout Christian ABDLs who don't struggle with the morality of it in the eyes of the church.
