There are no rules against ad homonyms. There is a rule against Ad Hominem attacks.
Homonyms are words that share the same spelling and may have the same pronunciation but different meanings.
Wikipedia fives the following example:Fluke can mean:
A fish, and a flatworm.
The end parts of an anchor.
The fins on a whale's tail.
A stroke of luck.
From the Religion Moderator's profile page:
Whereas posters may argue vigorously for and against beliefs on “open” Religion Forum threads it is never tolerable to use ad hominems in religious debate because they invariably lead to flame wars when the subject is one’s deeply held religious beliefs.Can't be used at all.
Changing the meaning is so...typical.
NOT a fluke, but at least there is consistency with your manner of debate.
