If you are reading a fanfic on your computer, and the author names one of his characters
A) something twee, and
B) after someone you despise,
you can easily solve the problem with a global search and replace. What’s more, you can use this to deal with overly elaborate Mary Sue names, foolish errors in historical naming, and the like. (As long as you remember what you’ve done, and never write any reviews of scholarly articles based solely on your version, that is.)
Now, let’s see. Wouldn’t it be better if people didn’t use Merlin’s name so gratuitously to name their characters? Aren’t there a wide variety of other magicians about, like Michael Scott, Gerald Fitzgerald the Wizard Earl, Jan Tregeagle, Virgil, and Maugis? And wouldn’t it be better if everyone with a pretentious name were renamed things like Bob or Ann? So… if somebody is named, say, Pretentius Myrllllyn, you just rename him Bob Tregeagle or Mac Mogie.
Ahhhh. Much better.
