Killahbee, non-plats have no control over the title under thier usernames. EF assigns those titles based on post count, etc, although administrators can change it as they see fit I believe.
If you'd like to argue semantics, then i'm sure you could make that case. My point, simply, is that the a fore mentioned sig could be construed as a)morally irreprehensible and b) malicious in intent towards the Catholic Church. As a Catholic, i don't personally find this offensive to me, but i would not doubt that it would be found so by many others.
Hopefully this displays my feelings a little more accurately.
