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.

There is much prejudice in the world. I see catholics as no better or worse than anglicans. All religions are very similar to me and should be equally rejected.

Yes, it is an awkward joke and a reminder that words change meaning and people should stop using dictionary definitions to "win" arguments that are not about the meaning of a word but about the concept it represents.

Yes, that's the dated definition of the word for the most part. So?

So what else is new?
