alt Hacker News"I often experience this. I saw that a co worker had written something about God in their Twitter bio. 'Are you a Christian?' 'I'm a Catholic' they replied. Any other denomination would say 'yes I'm a Christian'"
I'm going to suggest that if you would find it surprising to have your question answered with "Yes, Greek Orthodox," or "Yes, Southern Baptist," or "Yes, United Methodist," or some similar variation, your personal experience may not be as broad or definitive as you seem to think it is.
Well it's a common question I've asked of people during my life, and only catholics ever make that distinction, almost a correction. And there's a reason why - because they think it's the one true church. I'm not in the USA btw.
