If  you are going to be a religious you'ld be better off switching parties.

That is intentional - the grammatical irritation is nearly as bad as the irritation the religious himself causes.

So in order to combat irritation, you become irritating.

Okay then, Mr. Logic.

Probably.  Using adjectives as nouns is a perfectly normal grammatical construction.  Granted, it is more usual to have them used as plural nouns in English, but there’s nothing ungramatical about using the singular instead.

Dictionary.com lists "religious" as an adjective and as a plural noun.  I can't find any authority anywhere that claims that it's correct to use it as a singular noun.
