No, as long as we allow religiously related signatures, I think a picture of Jesus (or what most believe his likeness to be) is fine. However, if someone was clearly putting up an image of Jesus with some comments or in some other way clearly trying to inflame Christians on the board, that is where the mod's "latitude" in determining if it is allowed will come in.
Two things to keep in mind:
- As a general rule, we don't want to be any more restrictive that is absolutely necessary.
- It isn't ok for people to go out of their way to try and inflame select individuals or entire groups of individuals out of some type of sport or meanness.
