When I first started my character name was "Dixie Normus". It got flagged as inappropriate one day and when I logged in I was prompted to change my name before loging in. I didn't have to restart my character or anything, just change my name.

If it really makes you uncomfortable, then just flag it and SE will decide if it is inappropriate or not. Don't be afraid to speak up if it makes you feel uneasy. Chances are it is making others feel that way too.
