I agree. Jemima is a name more than the one stereotypical instance, as is Remus (Uncle Remus). NOBODY is harping on Remus despite the decades-long slamming of Song of the South. There's many people out there with the name Jemima. Should they legally change their names now?
We're talking about the use of a name of a brand of syrup that exists in one country vs the rest of the world, AND the entire history of Jemima uses.
