Yes, because those Catholics are not even Christians. Also, some Baptists claim they can trace their church all the way back to John the Baptist. The message must really be about John, huh.

Finger pointing? Business as usual in religi-town.

Etymologically the word comes from the Latin word pervertere meaning to make a bad choice or literally to make a bad turn and technically still does.
To use pervert to mean a sexual deviant is sheer laziness when one means sexual pervert
To use pervert to mean an apostate is simply shortening religious pervert owing to context
You can have a legal pervert
an industrial pervert
A moral pervert etc.

Making the assumption that "Pervert" simply always means sexual deviant is a modern laxity.

So what else is new?
