There is no assumption....those reading your user name gnostic will naturally think logically that you are a gnostic....you are being obtuse to pretend that those who assume you are a gnostic are reading things that are not there and that gnostic actually means agnostic to your sense of (il)logic... I mean, it would not take more than a few tics to change your avatar name to agnostic..
At the time I joined RF, I was reading and researching Gnosticism, especially from the Nag Hammadi codices.
It just a name, Ben.
Whether I called my avatar gnostic or agnostic, I don't think anyone wouldn't be making such a big fuss that you are making with my avatar's name.
If I called myself Jesus, Brahma, Vishnu, or Zeus, would you really believe that's my name? If I call myself tiger or dino, would you really think I am big striped cat or a dinosaur?
Stop making such big stink over name, Ben, because you are sounding petty.
