Telling him a word counts as profanity causes him to ask why that specific word is bad.
The accurate answer to "why is that particular word bad" is "because everyone else thinks it is." This answer is also the same for every bad word. And it's not an answer subject to nitpicking.
Saying a word doesn't count causes him to use it extra amounts if he perceives it is bad
If the word doesn't count, why is this a problem?
Is the word 'gay' profanity?
