Rather than flouncing and being rude, why don't you explain which bit of what I've said is stupid?
Oh, right, you can't. It makes no difference if a name is "real" or made up - most people won't be thinking "oh well old Adolf was a real person but Lucifer was an angel before he fell."
Connotations around names rarely relate to their origins - they relate to their use (Adolf has negative connotations for obvious reasons, as does Lucifer)
I think you're being deliberately obtuse over this for whatever reason.
So no, I'm not (being) stupid and I resent being called that quite a lot.
