Considering we are discussing it...
Let me start by saying I don't have a problem with what folks have as their taglines religous or not. If I were just joining the Assoc and tried to put something that describes me as my tagline only to be rejected because it was mildly religous, I probably wouldn't bother completing the joining process.
On the other hand, I firmly believe that people's actions, comments, and behavior should determine their prolonged membership. For example say someone chose to use porn for their avatar - I hope that would warrant a ban on posting until said user changed their avatar. If someone began preaching to folks on the forum, I would expect the same response.
I guess what I'm getting at is unless the tagline is outrageous in nature, as determined by the moderator :biggrin:, then there shouldn't be a problem with it. The community should respect that the Mod is doing his/her job and live with things such as avatars and taglines. If the Mod decided that porn avatars and prostelitizing were acceptable, then I expect the community would evaporate.
Further, the same question could include Advertising, as accoring to the AUP Advertising should only be listed on the Individual or Business Classifieds Forums - yet several folks have their websites listed in their taglines, and most of those websites offer products to be purchased.
But this is just my $.02....
