Most people who were raised Catholic continue to identify as catholic into adulthood even if they are essentially fully lapsed. A lot of places are culturally catholic so everyone is exposed to the culture- Friday fish frys in the Midwest is an example. That’s how you get people who say they’re Catholic while being alcoholics, never going to church, reading their Bible, or praying, not believing in any of the sacraments, being OK with porn, extramarital sex, birth control, abortion, etc.
I guarantee if any of those people were socializing with churchgoers, and spoke that way they’d be given embarrassed looks and taken aside at best and given a serious talk by their priest at worst.
I assume Nick isn’t speaking about his balldo at his Protestant church, as he knows that’s disgusting and embarrassing at heart and the people he socializes with in a church setting don’t want to hear that
