MOR is correct - Rule #5 does not prevent the mention of religion and religious activity. The reason why the person AFS1970 refers to has not attracted complaints may well be because they have not espoused their religion as being better than another etc.

We have had some very good threads, especially regarding kilts in religious situations without heat or arguing pros and cons.

And it is not just comments made about one religion alone that the rule gets cited against as has been claimed. Look at past threads and not just at the current ones to see what I mean.
