Since when are Catholics not Christians?

[Mrs. Don-o]

There's a mathematical symbol, I think, by which you can express succinctly that Catholics are a subset of Christians.

Or was that t'other way around?

Generally speaking, on public issues, when Christians are the target, Catholics are the bulls-eye.

[NorthMountain]

“Catholics” is a subset of “Christians”. One can be “anti-Catholic” without being “anti-Christian” (although that attitude would certainly be “unchristian”), but one cannot be “anti-Christian” without being “anti-Catholic”.

[Old Yeller]

Since when are Catholics not Christians?

When they remain Catholics.
