I'd say there are two different issues here. One is the Muhummad cartoons -
yes, those are offensive, and they are meant to be offensive. Whether they
belong in Wikipedia or not is another issue.
Ben's rotating cross may or may not be meant to be offensive - I'll take his
word on it that he didn't mean it to be offensive. All angles is actually
kind of clever. And as to an upside down cross being an offense to
Christianity - maybe you should have told that to Peter. Surely he's a
great offense to Christians everywhere. After all, we should never trust
the person Jesus selected, the rock upon which he built his church.
For that matter - the cross is meant to be offensive. It's an instruments
of torture and execution. Symbol of the rejection and execution of Jesus.
It's supposed to shock you.
