Had I said, "I am not a Catholic, I am a Christian", we would have started WW3.
Why can't you oblique semanticists just accept that people whom are not Catholic, but attend a church, or are of a particular denomination are also not protestant ?
I try to let people determine what they wish to be called relative to this kind of stuff.
I just thought “not Catholic” didn’t really help much since it still is in relation to and opposition to Catholic, as is “protestant.” Both seem to describe a confession that is defined by or rooted in opposition to... not much difference.
What denominational name do you wish to be called?
