Evangalical is also used as a slur...
and can mean a range of things...
No thanks...
I’m a Christian..
and therefore I am a Conservative..
I’ve never heard the term evangelical used as a slur, other than by a left-wing atheist.
Even Catholics don’t use it as a slur (at least not the ones I convers with).
I’m not sure where you get the idea the term has a negative connotation, but whatever...
