On the other hand the taking on of a new name for religious reasons is a perfectly respectable ancient pagan custom. The name Sheherazahde was given to me by my teachers at my initiation and I chose to use it when I am representing my faith. Although sometimes I don't, it depends on what point I am trying to make.
(Some people also have "secret" names that only their gods know. This is also a perfectly respectable ancient pagan custom. I don't really understand it, but I don't need too, that is why we have such a diverse community. But because secret names are *secret* they are not the subject here.) The other thing is titles. I am registered with the ULC so I could call myself Reverend if I wanted. But the "traditional" title for a Wiccan Priestess is Lady. People have made comment in my hearing about Lady being a pretentious title. I do not think it is any more pretentious than wanting people to call you "Revered one" (which is what "reverend" means), or "Father", standard proceedure in other religions. And I can see where there would be situations where calling oneself Reverend is a way of asserting ones right to be taken seriously by other religious professionals.
But if I am going to be on the same panel with someone calling herself "Sister John Joseph" I want to be called "Lady Sheherazahde".
To me, letting them call me Rev. Eva Snyder would be pretending to be something I am not just so I will fit in. In my religion my name is Sheherazahde and my title is Lady.
