Can non-Catholics be mentioned generically? For instance can they be referred to as "anti-Catholics" or "enemies of the Church"?
For instance, "non-Catholics speaking of the Rosary should be ignored" is not describing non-Catholic beliefs and is therefore ok for the caucus.
But saying "non-Catholics who say we worship Mary should be ignored" is describing beliefs of non-members and is not ok for a caucus, i.e. they would have an interest in speaking for themselves.
